Hello all,  I am trying to write a very short indicator that I can run in back test that will show me how deep a draw down goes during a set of tests. I am looking at Martingales type of trading systems in some EA's. If the draw downs are not too deep they will close out as profitable in the MQL4...

you know how on the charts, you can apply one indicator onto another by clicking, "apply to first indicator's data?" how can you do the same for programming in mql4? For example, I want to create a strategy that involves bollinger bands on RSI values. 

H1 EURUSD FROM 2001 with 2% risk per trade. I am looking at the areas that need improving. Test has been confirmed with a tick test (EA uses open prices).

Hi there! I'm new to the community and to the idea of algo trading, and I'm in need of help with coding my very first EA! What I did is that I downloaded EA from this link: https://book.mql4.com/samples/expert and tried to modify 'Trading criteria' in order to meet my expectations. Of course my...

Some of the EAs I have a lot if inputs. Example 20 symbols, 10 ten frames and 32 patterns. The configuration with in Metatrader is a not pretty.

The biggest (greatest) ticket number always corresponds to the last (the newest) order of the account. Is it true ?  Ticket(order A) > ticket(order B) ---> Order A was opened after the order B was. Is it true ? 

It is inconvenient not able to modify the order magic number. The order comment, too. 

What folder which MQL4 keep history data ? Thank you

Hi, When testing EA's, are you more concerned about the max or relative drawdown, perhaps both? I think max drawdown is more important as this determines the drop from the "balance" whereas relative determines the drop from the "equity". This way I know what I could expect from the worst possible

Hello all, On currency tickers (e.g EURUSD)  I get the chart and the H1 or H4 data is bar aligned on the hour so I get bars that are timestamped as 15:00, 16:00 or whatever. The problem is that for some tickers (#AA and #C) I get the H1 and H4 data bar aligned on the half hour, so the bars are...

As humans, we can readily tell when we have live data feed and when we don't.  But just try to write a code for insertion into a custom indicator that can tell, during times when there is no live feed (weekends, holidays, etc.) that there is no live data feed!   I don't think it can be done, but if...

Good afternoon. Partly as a continuation of the "Absolute Courses" thread (by virtue of being here), and partly anew (by virtue of the basis on new ideas), I am continuing with demo trading. At first, on a demo account. For about a week or two, to analyze a new idea. After that I will repeat demo

This was an indicator that I am trying to make into an EA.  I am trying to do one thing at a time.  I am just working the buy side.  Pls notice that strategy tester placed a buy order about 16 pips above the high of the bar.  Why?

Hello all,  I was trying to make a scalping EA, but I can't figure this thing out: It immediately closes all it's positions. Been looking over it for hours now, hope one of you can see it. I guess it has to do with the TP/SL. The reason I don't use the OrderSend function for that, is because my...

Hi there,  I was wondering the if the community could help me out in respect to defining what 'current chart' means in https://docs.mql4.com/series/iBars.  We have the following in our code: int bar = iBars(symbol, PERIOD_M5);   What we don't understand:  When we loop over the symbol set, we get a...
