I'm writing an indicator with a switch-case statement and it's behaving in a way that I can't understand.  I'm wondering if someone might have some insight?  This switch-case runs a state machine. Once in the upwardTrend or downwardTrend

Wondering if someone can shed some light on an issue I'm having in my OnCalculate() function.  I'm trying to do three iterations of calculations when the function gets called, but I can't seem to get anything to happen in the third

I'm coding a volume-based custom indicator with two signals and for some reason that I just can't figure out the second line won't draw.  The name of the buffer that won't draw is relVolumeMA in the code below.  I'm not a programming

I've make a custom indicator, and for some reason the output is different when I am using it in the strategy tester than it is when I just drop it onto a chart.  I'm attaching a screenshot showing the indicator twice in the same window. 

I'm having an issue where I've written an indicator and am now using it to backtest a strategy.  I start my backtester in visual mode and then drop my indicator onto the chart.  When I do that, the lines in the indicator don't ever update

I am trying to put together an indicator that would show the signal line from the ADX indicator from the next three higher timeframes all on one indicator, the only variation being that if -DI is above +DI it will show as a negative value.  I've

I am trying to write an indicator that uses information from the ADX indicator and am trying to pull data from the ADX indicator the same way I do in my EA's, as follows: ADX_Signal[i] = iADX(NULL, 0, 14, PRICE_CLOSE, MODE_MAIN, i);    //

I've been using the GlobalVariable....() functions to create my global variables for my EA but am wondering if I'm making life too difficult for myself. I will be running this EA on multiple charts in the same terminal at the same time and have been

I am trying to create an array of structs, everything I find online indicates there shouldn't be a problem with that, but I can't seem to get my code to compile when I try to do this.  Here is what I am trying to do: // Heiken Ashi Candle Struct

I'd like to write an EA that looks at heiken ashi candles instead of normal candles but am not sure how to do that (I'm still pretty new at this).  Do I just write a standard EA using the Open[], High[], Low[], Close[] commands and drop it on a

I've written my EA so that it always places pending orders .  If I want my program to go back later and check if that pending order has been activated what is the easiest way to determine that?  If the order gets activated, does the

Is it possible to use the debugger with historical data with MQL4?  I see the button for it and the tab in the options menu to set it up but the 'Start on History Data' button is greyed out

If I use time functions in my EA will they function properly in the strategy tester ?  For example, if I use the Time[i] function to detect when a new bar appears will that work in the tester

I was hoping someone could help me understand the strategy tester a little better (newbie here).  I've am using the OnTimer() function in my EA basically as follows:  - Every 1 second the OnTimer() function gets called  - I do stuff in

I am having an interesting issue where I call the Comment() function each time I get a new tick and instead of clearing the existing comment prior to writing the new comment it will simply write the new comment below the old comments.  Sooner or
