K-2SO:

Where did you get that conclusion from?^ ^

The way margin is calculated for XAUUSD, also Forex there profit is futures, not what we are trying to calculate.

1. Be careful. So as not to bother you to go to the right page I will pull part of the table here.

SYMBOL_TRADE_CALC_MODE

Mode of contract value calculation

ENUM_SYMBOL_CALC_MODE

ENUM_SYMBOL_CALC_MODE

Identifier	Description	Formula
SYMBOL_CALC_MODE_FOREX	Forex mode - profit and margin calculation for Forex	Margin:LotsContract_Size/Leverage Profit: (close_price-open_price)Contract_Size*Lots
SYMBOL_CALC_MODE_FUTURES	Futures mode - calculate margin and profit for futures	Margin: Lots InitialMarginPercentage/100 Profit: (close_price-open_price)TickPrice/TickSizeLots
SYMBOL_CALC_MODE_CFD	CFD mode - calculation of margin and profit for CFD	Margin: Lots ContractSizeMarketPricePercentage/100 Profit: (close_price-open_price)Contract_Size*Lots

2. Don't tamper with the screenshots.

Where SYMBOL_CALC_MODE Forex or CFD is counting correctly.

3. I won't rewrite the script anymore. All I wanted to understand from this thread, I already understood. Thanks to the author of the theme.

Alexey, I am amazed at your persistence. The topic is really 100% covered. It was a pleasure to read and follow the thread.

Well done!

Write an article about margin, if it's not too much trouble.

Good luck to you!

I am just more confused again. What does this have to do with calculating the value of the contract when we're calculating the margin? And where did I change the screenshots if I only added new ones? I also mentioned XAUUSD, but I was too lazy to add screenshots.

Thank you for your kind words, but writing is not my craft. Besides, mql4 developers are not very interested in articles about mql4, it seems to me. In mql5, everything or almost everything is available in standard functions.

If you have the desire and ability, go ahead and write, I don't mind. If there will be references to me, thank you, there won't be, well, it's not really necessary...

Yes, even though the formulas were originally taken from the table depending on how the contract value was calculated.

If you were too lazy to do that, you don't need to mention it. Programmers often perceive information just like a computer does - what it sees is what it processes. How can you understand it if you're talking about gold and you're attaching EURUSD to a screenshot...

That's how I started, but then I got sucked in like a swamp. Once upon a time, a long time ago, I wrote an information indicator for myself and for the sake of training. I wanted to insert margin for each order and then for the sum of orders of each symbol, but nothing worked then. And when I understood the essence of the margin percentage, I was eager to do what I was unable to do at that time... I don`t use that indicator now, but I`ve improved my knowledge... Thanks again to the author of the theme...

If you are lazy, you do not need to mention it. Very often programmers perceive information absolutely like a computer, what it sees and processes. How can you understand if you're talking about gold, but you're attaching EURUSD...

Ok, let's leave gold aside to avoid confusion and leave aside the fact that you didn't answer why you calculated the margin using the contract calculation method and not the margin method as stated in the XAUUSD specification.

Specifically, here is again a screenshot of the EURUSD specification:

I wasn't even trying to go anywhere. Here's the answer.

How to get "Percentage of Margin" programmatically

Yes at that the formulas are originally taken from the table depending on how the contract value is calculated.

You can only add that this is the way the terminal developers have designed it.

You have to correct the formulas separately for such a specific brokerage company. It is very simple, if all the normal margin currency is the base currency of the instrument, and this miracle is taken as a margin currency is strictly USD or the currency of the deposit, then it should be calculated taking into account.

1.We get margin in the currency of the deposit

double margin = MarketInfo(symbol, MODE_MARGINREQUIRED);

multiply it by the lot and that's it!!! All you have to do is to run it in the debugger and see what data is obtained. It's all shoved in here already.

This may be correct, but it is not for me to judge.

You have to adjust the formulas separately for such a specific BC.

That's my point - there is no universal formula for calculating the deposit. So there may also be problems with calculating percentage.
