Risk tab

The risk tab can help you assess current and potential risk and reward profile. Using a simple algorithm, the EA 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 expert advisor 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.

1. Include orders button to switch between All, Open only, and Pending only to filter the trades that the EA will include in its risk calculations.
2. (A) Ignore orders without stop-loss — if ticked, PS will ignore all risk coming from orders and positions without SL value set. Can be useful if you prefer not to set stop-loss for some of your trades.

How to use Position Sizer to calculate position size and to trade

Using this expert advisor is very simple if your main aim is to calculate the position size based on your stop-loss and the current market parameters and then to execute the trade based on that calculated position size.

1. Attaching Position Sizer 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.
2. 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.
3. If not, you can freely change the stop-loss — either by dragging the stop-loss line on the chart or by entering the value into the stop-loss input in the panel. You can also set your stop-loss as a distance in points by turning on the respective input parameter.
4. You can set your take-profit the same way. Additionally, you can quickly set the TP equal to the current SL value (or with some preset multiplier) by clicking the Take-profit button. Similar to the stop-loss, the take-profit can be set as distance in points if the respective input parameter is turned on. Multiple take-profit levels are supported when TakeProfitsNumber input parameter is set to a value greater than 1. You can also add and remove take-profits using the panel buttons.
5. If you turn ATR settings on via the EA's input parameters, you can also control the ATR values for stop-loss and take-profit calculation.
6. Adding a take-profit will turn on the display of Reward and Reward/risk ratio for your information.
7. 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 changed manually. When Pending or Stop Limit (in MT5) order is used, the Entry level can be set either via panel's input or by dragging the chart line.
8. The EA will warn if the Entry level is too close to the current price in the Pending order mode and if the Stop-loss or Take-profit level is too close to the Entry level.
9. 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.
10. Switching the account size from balance to equity or to balance minus portfolio risk can be useful in some cases and is done by one or two clicks on the respective button.
11. Adjusting the risk tolerance can be done in two ways: by setting the percentage risk value or by setting the money risk value. Both are done via the input fields in the panel. You can also use the quick risk setting buttons if you need to switch risk per trade often.
12. 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.
13. The Margin tab is not necessary either if your goal is to calculate the optimal position size based on your risk and stop-loss. This tab will inform you on the 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.
14. The 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.
15. The Trading tab will help you to execute the actual trade and control how it is done.

Trading

You can use the position size output of this EA to open trades manually in the same or some other platform. Alternatively, you can use its trading capability to open trades based on the calculated position size and with the given entry, SL, and TP levels. You can either use the Trade button on the Trading tab or the hotkey (set via input parameters). Additionally, you can turn on more trade buttons: on the Main tab and near the Entry line.

How to enable ATR parameters?

Below you can see a short demonstration of how to enable Average True Range (ATR) settings in the Position Sizer expert advisor to set ATR-based stop-loss or take-profit levels:

Manual backtesting with Position Sizer

In MetaTrader 4 (but not in MetaTrader 5), you can use the Position Sizer in the visual mode of the Strategy Tester to backtest your manual trading strategies. It will calculate the position size and place the trades as usual. You will be able to monitor their profit/loss and close them when necessary. In the end, you will be able to see the standard MT4 backtesting report. The buttons that let you close trades display profit/loss in the square brackets with the points followed by currency P&L.

The panel cannot be dragged on the screen, but its position can be set via input parameters. The interaction with the EA is rather slow in the Strategy Tester because there are no direct chart events — everything is processed only when a new tick arrives.

Demonstration video on input parameters

You can see a visual demonstration of how the Position Sizer's input parameters (as of version 3.00) work in this detailed video:

Screenshots

Main tab

The main tab is the biggest one and looks nice on any background — this one is white for example. The take-profit and stop-loss lines' colors have been changed via input parameters for better readability. The order type is set to Stop Limit here, so the purple stop price line is also visible on the chart.

Risk tab

Black background color and chart grid do not interfere with the panel as you can see on this screenshot of the Risk tab. The panel is set to a dark mode, to reduce the screen brightness. The risk outputs show Infinity as there is, apparently, a sell order without stop-loss.

Margin tab

Even the wildest color scheme works well with Position Sizer. In this case, cyan background is combined with green and red candlesticks. Stop-loss color is set to black.

Swaps tab

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.

Trading tab

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 purposes.

Minimized panel

Minimizing the panel in one click makes it completely non-obtrusive and allows trader to easily see the entire chart.

Installation

To install the expert advisor, make sure that you copy the entire folder from the archive to \MQL4\Experts\ or \MQL5\Experts\ (if you are on MetaTrader 5).

The EA folder should contain the following files and the Translations subfolder:

• Defines.mqh
• Position Sizer.mq4 or Position Sizer.mq5
• Position Sizer.mqh
• Position Sizer Trading.mqh
• errordescription.mqh (MT5 only)
• TesterSupport.mqh (MT4 only)
• EF-Icon-64x64px.ico

You need to compile Position Sizer.mq4 (or Position Sizer.mq5), not any of the other files.

This how-to video explains how to install the Position Sizer EA for MetaTrader 5, but the process is quite similar for MetaTrader 4:

Installing Position Sizer on macOS

The installation process on newer macOS devices (M1, M2, M3, M3 Pro, M3 Max, etc.) is somewhat different from installing the Position Sizer on Windows. Please watch this video to see how the Position Sizer is installed on a MetaTrader for macOS (via WINE):

If the method described in the video doesn't work for you, you can try following these steps (given for the MT5 version, but the process is very similar for MT4):

1. Run MetaEditor (press F4 when in MetaTrader).
2. Drag the files from the downloaded archive one by one to MetaEditor.
3. Use File->Save As to save them to the proposed location. Translation files should be saved into the Translations subfolder in that location.
4. You can save all files except for the EF-Icon-64x64px.ico file in that way. Omit EF-Icon-64x64px.ico.
5. Open Position Sizer.mq5.
6. Find the following line and either remove it or comment it out:

    #property icon      "EF-Icon-64x64px.ico"

7. You can now either compile Position Sizer.mq5 or restart MetaTrader (for the compilation to be performed automatically).

---

Translating Position Sizer

The panel's interface can be translated. In addition to English, the following languages are supported: Arabic, Chinese (Simplified), Chinese (Traditional), Portuguese (Brazilian), Spanish, Russian, Ukrainian. More languages will be added in the future.

You can switch the language by editing and then compiling the Position Sizer.mq4 or Position Sizer.mq5 file. You just need to uncomment the respective line at the top of the file and click the compile button.

Here is an example screenshot with the line for enabling the Ukrainian language highlighted:

And here it is shown uncommented with the compile button highlighted:

It is actually easy to create your own custom translation of the Position Sizer's interface. It doesn't require any coding skills. The translation file consists of just a few hundred terms and phrases.

Frequently asked questions

I get compilation errors when compiling Position Sizer. How do I solve this?

First, make sure that you are compiling the correct file — Position Sizer.mq4 in MetaTrader 4 or Position Sizer.mq5 in MetaTrader 5. Second, make sure that the other files — Defines.mqh, Position Sizer.mqh, Position Sizer Trading.mqh, and errordescription.mqh (in MT5) — are placed in the same folder as the file you compile. If the problem isn't solved, please post in the official discussion thread, stating the version of Position Sizer, version of MetaTrader, and providing a copy or a screenshot of the compilation errors.

I installed the expert advisor 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 expert advisors in MetaTrader's Navigator window and press Enter. MetaEditor will open the EA's source code. Now press F7. See the answer to the question above if there are compilation errors.

Position Sizer doesn't work correctly. What do I do?

To help you with the issue, I would need to know what version of the EA you are using, what version of MetaTrader (including the 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:

I enter, let's say, 1% risk, but the Results column shows 0.87%. I want to risk, let's say $5,000, but end up risking $4,350. Why?

The most probable reason for that is that increasing the position size by the minimum possible increment would lead to a position size with a risk greater than the given percentage. The Position Sizer rounds the position size down in such cases, aiming to reduce the actual risk rather than to overshoot the specified value. You can always set the CalculateUnadjustedPositionSize input parameter to true to make the Position Sizer to show the exact calculated position size, but you won't be able to open such a trade with this broker because it won't comply with the broker's restrictions on the minimum position volume step.
