This indicator is an evolution of the free online tool by the same name. Position Size Calculator is available for both MT4 and MT5, but the MT5 version looks differently and provides better functionality because the platform itself is more advanced.
The main tab of the panel provides the primary control over the indicator's functions and serves to output the most important calculation results — position size, risk, reward, and risk-to-reward ratio. The following controls and outputs are available:
Indicator's version number.
Spread value in ticks.
Minimization button to fold down the panel.
Close button to remove the indicator from the chart.

Commission size per lot (one-way) — set it if your broker charges commission and you want it included into risk size when calculating position size.
Account size button switches between balance, equity, and "Balance - CPR"; the latter being account balance less the current portfolio risk as calculated on the Risk tab.
Account size in account currency units.
Account size asterisk signals that additional funds are set via input parameters; the funds were added to the account size value.
Quick risk button #1 — first button to quickly set percentage risk value.
Quick risk button #2 — second button to quickly set percentage risk value.
Risk input — you can set your tolerated risk in percentage of the account size. If you set your risk via Risk money input, percentage risk will be calculated based on that input.
Risk money input — you can set your tolerated risk in account currency units. If you set your risk via Risk percentage input, money risk will be calculated based on that input.

Reward/risk (input) — input reward divided by input risk.
Reward/risk ratio (result) — reward result divided by risk result.
Position size — actual position size calculation output. You can modify it yourself if you want to calculate your risk based on position size.
Pip value per calculated position size.
The risk tab can help you assess current and potential risk and reward profile. Using simple algorithm, the indicator calculates the risk of the currently open positions and pending orders based on their stop-loss levels (or lack thereof). It also assesses the potential reward of already opened positions and the position calculated by the indicator based on take-profit levels. The employed risk analysis method does not account for complex situations involving hedged orders and positions. You can use the Risk Calculator indicator for a deeper portfolio risk analysis. You can control the Risk tab using two checkboxes and see the calculation results in ten output fields:
Count pending orders — if checked, the indicator will also attempt to calculate the risk of pending orders in addition to currently open positions.
Ignore orders without stop-loss/take-profit — if checked, will simply ignore all risk coming from orders and positions without SL/TP value set. Can be useful if you prefer not to set stop-loss/take-profit for some of your trades.
Current portfolio risk (currency) — shows the risk in currency units without the position that is currently being calculated by this indicator.
Potential portfolio risk (currency) — shows the risk in currency units as if you have already opened a position that is currently calculated by this indicator.
Current portfolio risk (%) — same as Current portfolio risk (currency) but in percentage to the account size.
Potential portfolio risk (%) — same as Potential portfolio risk (currency) but in percentage to the account size.
Current portfolio reward (currency) — shows the reward in currency units without the position that is currently being calculated by this indicator.
Potential portfolio reward (currency) — shows the reward in currency units as if you have already opened a position that is currently calculated by this indicator.
Current portfolio reward (%) — same as Current portfolio reward (currency) but in percentage to the account size.
Potential portfolio reward (%) — same as Potential portfolio reward (currency) but in percentage to the account size.
Current portfolio lots — the total size of the currently open positions in lots.
Potential portfolio lots — the total size in lots of the open positions plus the one, which is currently being calculated by this indicator.
The margin tab provides information about the calculated position's margin, amount of used and available margin after opening the calculated position, and the biggest possible position size considering the current available margin and leverage. The tab has only one input and five output fields:
Position margin shows the margin that will be used for the calculated position. Negative value means that the future used margin will be lower than the current due to lower requirement for margin of the hedged positions.
Future used margin is calculated based on the current used margin and position margin.
Future free margin shows how much free margin you will have left after opening the calculated position.
Custom leverage input lets you set your own leverage for all the margin calculations done by this indicator.
Default leverage shows the account's actual leverage for your reference.
Symbol leverage shows the actual leverage for the current trading instrument. It is calculated based on required margin and contract size/value. It may be inaccurate in some cases.
Maximum position size by margin displays the biggest trade you can take with your currently available free margin and leverage.
The swaps tab displays details on the overnight interest payments associated with the current trading instrument and calculated position size. It shows swaps type, nominal swaps, daily, yearly, per lot, per calculated position size, and both for long and short positions:
Type shows the type of swaps used by the broker for the current trading instrument. Can be one of several kinds: pips/points, base currency, interest, account currency, margin currency, reopening.
Triple swap shows the day of week when triple swaps are charged/paid (to account for Saturday and Sunday).

Daily swap per PS (Short) — daily swap paid or charged by a broker for short positions in account currency for calculated position size (on the Main tab).
Yearly swap per lot (Long) — swap paid or charged by a broker for long positions in account currency per lot. Calculated for a period of 360 days.
Yearly swap per lot (Short) — swap paid or charged by a broker for short positions in account currency per lot. Calculated for a period of 360 days.
Yearly swap per PS (Long) — swap paid or charged by a broker for long positions in account currency for calculated position size (on the Main tab). Calculated for a period of 360 days.
Yearly swap per PS (Short) — swap paid or charged by a broker for short positions in account currency for calculated position size (on the Main tab). Calculated for a period of 360 days.
Position size duplicates the display of the position size calculated by the indicator on the Main tab.
The script tab serves to provide you with some control over the trading script. You may skip this tab if you are not using PSC-Trader.
Magic number — Magic number that will be assigned to the orders and positions opened using the script.
Order commentary — commentary for orders and positions opened using the script.
Disable trading when lines are hidden — a simple checkbox to prevent script from opening a position when you have chosen to hide the lines via the Main tab.
Fill take-profits inwards — a button to fill multiple take-profit fields equidistantly from Entry level to main Take-Profit level.
Fill take-profits outwards — a button to fill multiple take-profit fields equidistantly with the main Take-Profit level as the closest one.
Multiple take-profit levels — a number (set via ScriptTakePorfitsNumber input parameter) of take-profits to divide the position among. The first take-profit is always the same as the one set on the Main tab.
Shares of to divide the position size — each take-profit level is assigned its percentage of the total position size calculated on the Main tab.
Max slippage — maximum tolerable slippage value (in broker pips) that will be used in trading functions of the script.
Max spread — the script will not trade if current spread is wider than the value given here.
Max Entry/SL distance — the script will not trade if distance between the Entry level and Stop-Loss level becomes greater than this value.
Min Entry/SL distance — the script will not trade if distance between the Entry level and Stop-Loss level becomes less than this value.
Max position size — if calculated position size exceeds this value (in lots), the script will only open a trade of the size given in this field.
Subtract open positions volume — if checked, the script will calculate the total open volume for a given trading instrument and will subtract it from the calculated position size, so the resulting volume after a new trade opens is equal to the calculated position size.
Subtract pending orders volume — if checked, the script will calculate the total volume of all pending orders on a given trading instrument and will subtract it from the calculated position size, so the resulting volume after a new trade opens is equal to the calculated position size.
Do not apply stop-loss — if checked, the script will open a trade without stop-loss. This can be useful if you use a separate expert advisor or some other means to trigger your stop-loss.
Do not apply take-profit — if checked, the script will open a trade without take-profit. This can be useful if you use a separate expert advisor or some other means to trigger your take-profit.
Ask for confirmation — if checked, the script will ask for confirmation before trading.
Using this indicator is very simple if your main aim is to calculate the position size based on your stop-loss and current market parameters.
Attaching Position Size Calculator to a chart will automatically set an entry level to the current price, preparing for a market buy order. Stop-loss level will be set to the nearest low. Take-profit will be turned off.
Now, you can already use its position size output to enter a trade if you planned a market buy order with SL set to the low of the current bar and with 1% of balance risk. You can also change the position size field manually to calculate the risk based on its value.
If not, you can freely change the stop-loss — either by dragging the stop-loss line on chart or by entering the value into the stop-loss input in the panel. You can also set stop-loss as distance in pips by turning on the respective input parameter.
You can set take-profit the same way. Additionally, you can quickly set TP equal to the current SL value (or with some preset multiplier) by clicking the Take-profit button. Similarly to stop-loss, take-profit can be set as distance in pips if the respective input parameter is turned on.
If you turn on ATR settings via the indicator's input parameters, you can also control the ATR values for stop-loss and take-profit calculation.
Adding take-profit will turn on the display of Reward and Reward/risk ratio for your information.
Switching the type of order from Instant to Pending (and backwards) is done with the order type button. When Instant order is used, the Entry level will trail the current price (Bid or Ask) and cannot be manually changed. When Pending order is used, the Entry level can be set either via panel's input or by dragging the chart line.
The indicator will warn if the Entry level is too close to the current price in Pending order mode and if the Stop-loss or Take-profit level are too close to the Entry level.
You can set the size of commission (one-way) applied by your broker if you want your potential loss to be calculated including this cost of trading.
Switching account size from balance to equity or to balance minus portfolio risk can be useful in some cases and is done by a one or two clicks on the respective button.
Adjusting the risk tolerance can be done in two ways: by setting percentage risk value or by setting money risk value. Both are done via input fields in the panel. You can also use quick risk setting buttons if you need to switch risk per trade often.
Moving on to the Risk tab of the panel is completely optional and provides information about your current and potential risk and reward. You can control how pending orders and orders without stop-loss/take-profit are treated in this tab.
Margin tab is not necessary too if your goal is to calculate the optimal position size based on your risk and stop-loss. This tab will inform you on amount of free and used margin resulting from your position. It will also show you what is the biggest position size that you can open with your current free margin and leverage. A custom leverage can be entered if need arises.
Swaps tab can be consulted if you wish to know how costly the daily rollover will be for your position. It will be especially useful if you are using a carry trade strategy.
Script tab will help you to control how the PSC-Trader script behaves if you use it for position opening.

Input parameters explanation video
This explanation video below demonstrates how changing the parameters described above change the Position Size Calculator's behavior:
The main tab is the biggest one and looks nice on any background — this one is white for example. Take-profit line's color has been changed to orange via an input parameter for better readability. The order type is set to Stop Limit here, so the purple stop price line is also visible on the chart.
Black background color and chart grid do not interfere with the panel as you can see on this screenshot of the Risk tab. The risk outputs show Infinity as there is, apparently, a sell order without stop-loss.
Even the wildest color scheme works well with Position Size Calculator. In this case, cyan background is combined with green and red candlesticks. Stop-loss color is set to black.
This example shows swaps tab with a classic black and white color scheme chart. This broker is charging some serious rollover fees for margin trading in Bitcoin.
When the panel is set to background, it becomes transparent and you can easily analyze the exposed chart. At the same time, you are able to see the values used for trading script management on this tab.
Minimizing the panel in one click makes it completely non-obtrusive and allows trader to easily see the whole chart.
Downloads (ver. 2.33, 2020-12-13)
Position Size Calculator is being developed via a dedicated GitHub repository. You are encouraged to actively participate in the improvement of this indicator by submitting your own features via pull-requests and by reviewing existing suggestions, changes, fixes, and so on.
To install the indicator, make sure that you copy all three files to /MQL4/Indicators/ or /MQL5/Indicators/ (if you are on MetaTrader 5) or to the same subfolder there:
PositionSizeCalculator.mq4 or PositionSizeCalculator.mq5
You need to compile PositionSizeCalculator.mq4 (or PositionSizeCalculator.mq5) not the other two.
This how-to video explains how to install Position Size Calculator in MetaTrader 5 platform, but the process is very similar for MetaTraer 4:
You can use the position size output of this indicator to open trades manually in the same or in some other platform. Additionally, you can use a custom trading script that will open trades based on the calculated position size and with the given entry, SL, and TP levels. Just copy it to /MQL4/Scripts/ (or /MQL5/Scripts/) subfolder of your platform's data folder. After compilation, It will become available in the Navigator subwindow of your trading terminal under Scripts as PSC-Trader. You can also set a hotkey to run this script if you want to open orders really fast. The script's behavior is controlled via Script tab of the Position Size Calculator.
Trading script execution example with confirmation to open a position:
Do you have any suggestions or questions regarding this indicator? You can always discuss Position Size Calculator with other traders and MQL programmers in the forum.

Frequently asked questions
I get compilation errors when compiling Position Size Calculator. How do I solve this?
First, make sure that you are compiling the correct file —PositionSizeCalculator.mq4 in MetaTrader 4 or PositionSizeCalculator.mq5 in MetaTrader 5. Second, make sure that the other two files — Defines.mqh and PositionSizeCalculator.mqh — are placed in the same folder as the one you compile. If the problem isn't solved, please post in the official discussion thread, stating the version of Position Size Calculator, version of MetaTrader, and providing a copy or a screenshot of the compilation errors.
I installed the indicator but when I add it to a chart, nothing happens. Why?
Most likely, you need to compile it. To do this, left-click it in the list of indicators in MetaTrader's Navigator window and press Enter. MetaEditor will open the calculator's source code. Now press F7. See the answer to the question above if there are compilation errors.
The indicator/script doesn't work right. What do I do?
To help you with the issue, I would need to know what version of the indicator/script you are using, what version of MetaTrader (including Build number) you are using, and also what broker, account type, and account currency you are trying it on. Additionally, please provide the output in the Experts tab of your Terminal/Toolbox subwindow:
