tim4dexlus #: and if i want to compare it with current price. so if i want to compare for example EURUSD Open ask price with EURUSD current bid price is that possible?

The Open ask price, no! That is a Bid price. But current price, yes! If you synchronise the detection of a new bar, then that will give you the current open ask and bid price, which you can save for further reference.

The predefined Variables

Variable	Value
Ask	The latest known seller's price (ask price) of the current symbol
Bid	The latest known buyer's price (offer price, bid price) of the current symbol

For current prices of different symbols, use ...

SymbolInfoDouble

Returns the double value of the symbol for the corresponding property

ENUM_SYMBOL_INFO_DOUBLE

Identifier	Description	Type
SYMBOL_BID	Bid - best sell offer	double
SYMBOL_ASK	Ask - best buy offer	double

Is it not obvious? Bid and Ask prices are information about Symbols, which in turn is about Market information ...

• MQL4 Reference → Market Info → SymbolInfoDouble

that is the whole problem. i understand the history logic pretty well. it is the current info logic in metatrader i struggle with. i also started working first with history because that looked the easiest to me to check, incase i made an error. but going from history to current values. everything is different to me. it feels like it is 2 different languages in 1 editor.

I think that maybe the reason you are having a difficult time understanding the logic, is because you have not taken the time to first learn to properly trade manually on the platform.

Unless you fully understand the mechanics and intricacies of manual trading, you will have difficulty programming it in MQL code.

i trade already over 8 years using metatrader. now to say that i am highly successful would be a lie, but i never used the programming part of it, since 3 months ago i started learning metatrader editor. sure i can make easy script to set orders. i can also easily make a crossover ma indicator for example. but when it gets more complicated i struggle for current values, but that has more to do that i do not find the right functions like symbolinfodouble for example. market info i knew already, but it was that next step, but now with symbolinfodouble it becomes much more clear to me. so thanks a lot for that!
