Position Sizer

[LittleBB]

I see. The risk % you see in the left column (captioned Input) is the risk % that you enter - the one you want. The risk % in the right column (captioned Result) and in the SL line's additional label is the resulting risk - the percentage you'll lose if you open the calculated trade.

There is a difference between the Input risk and Result risk because the EA would calculate a higher position size given your risk and SL, but it would be above the maximum position size, which is 100 in your case. Since, it cannot increase the position size, when you move the SL closer to your entry, the Result risk goes down.

Most likely, the position size isn't calculating correctly here (not sure how much is 100 lots of NAS100 is at your broker). This is probably caused by incorrect info returned to the EA by the trading server due to its misconfiguration.

I'm having a similar issue in MT5. I do not adjust the lot size, I only change the % risk. The % entered and the results side is off by .01% If .03 is entered, it is calculating and showing on the SL line as .02 even though the results column shows .03

This happens with larger % as well. 1% displays on the SL line as .99%

Is this by design or a potential bug?

Edit: I tried increasing it by .01% and it shows the lower % on the SL line but the result is closer to the higher % I increased it to.

Feature Request: Please consider adding an option that will display only % or only $ on the line. I always turn off the options to display my account size because it distracts me when I trade but I love seeing the % value there.

If the issue is similar, then it is probably caused by the same thing, but it would really help to see the screenshots of the problem you describe.

@Enivid I think he mentioned this..


But I hope most of the traders don't need to worry about micro size % miss match.

Hello Enivid,
Thanks for your amazing job.
I would like to ask if it is possible to have a Breakeven method based on How much % our position is in profit... (for example +50% of a 1:2 Risk/Reward) it will move the SL of "+ a tot of pips" from the entry.
Also it could be possible to have a Partial Profit, with the same trade? Instead to open multiple trades at once.
Thanks again.

Thank you Enrich, yes that is what I'm talking about. I didn't notice the issue in the non-EA version. When it comes to risk, I have to know that the tool is accurate. In your screenshot the tool is off by .03 %.

I'm trading with MFF and when I enter the same value as you did (.3% risk), it shows off by the same .01%.

I see. That looks like some rounding errors for the line label. I'll fix it in the next version of the EA. The Result column output should be the correct one.

I've installed the position size calculator on my MT5 platform, but it's not working. I copied and pasted it inside the experts folder, but it's not showing up. Please help.

You probably need to compile the one file mentioned here: https://www.earnforex.com/metatrader-expert-advisors/Position-Sizer/#Installation

hello everyone

Thank you so much for developing this wonderful expert

In some strategies, we have to calculate our trading volume based on profit and then enter the SL based on profit.
For example, I enter a trading position for 10 pips profit , and as a result, the SL is set at 5 pips from the entry point.
I did not see this possibility in Expert
If this item is added, it will be very nice

I received this error when attempting to use PS this afternoon (MT5). AutoTrading option is turned on. I turned it off and back on but the same error message happens. In this message, is 'client' my installation of MT5 or the prop firm (MFF)?

No idea. That can be either. Is autotrading also enabled for the EA specifically - press F7 and check on the Common tab (Allow live trading).
If it's enabled, then it's MFF that doesn't allow autotrading execution.

For some reason that box wasn't checked. I checked it and now it works. Thank you Enivid.

Hi there, thanks for the building this amazing tool.
My question: does the script take the spread into consideration when calculating the lot size? In other words, does it add to the SL distance in the position size calculation formula.

Thank you

Why would it? You set explicit SL, it calculates the position size based on your risk and that SL. Spread has nothing to do with this.

Hi, I just downloaded the program for MT5 on my Mac, but I can't copy the folder to MT5. It doesn't make me paste this folder in / MQL5 / Experts / also I don't understand how to compile the Position Sizer.mq5 file

Try what's described in this post for macOS installation. You should only try compiling after you copied the folder.

It would help to see the top of the error output - the first errors it prints.
