Purchased two MTF indicators, get "version of {indicator} is obsolete; please recompile it", why?
I've purchased two MTF indicators from two different developers. Any time I toggle the timeframe to something other than "current" I get the error in Experts tab "version of {indicator} is obsolete; please recompile it". What is going on? Is it that difficult to create MTF indicators in MQL5
How to get iMA( buffer to plot when referencing iMA( on a higher TF?
Hi, I was able to get the iMA( to successfully plot a moving average . Suppose I wanted to plot a higher timeframe MA? In the code below, there's an input of choosing a higher timeframe with the variable "TF". For example, if I wanted to plot the M30 moving average when the indicator is on a M15
How to create a moving average function and plot it?
Hi, My skills in MQL5 are quite weak compared to MQL4 and I've never been able to truly carry over referencing indicators in MQL5. In the example below, the high/low channels plot just fine; however, the moving average does not plot, at least not correctly. I'm attempting to re-write the iMA(
ChartRedraw, best way to use?
Hi, I know MQL5 demands ChartRedraw to update GUI on a chart. However, I'm probably not using it optimally. Consider the following scenario... I have 5 indicators each which must update the properties of 100 objects each, or any one object at a time, either from a new tick, on a timer, or an

MT5 convert from MT4 Indicator not plotting properly
Hi, I am close to converting an indicator from MT4 to MT5; however, the converted indicator is not plotting properly. In addition, there is a "divide by zero" error on line 73/column 18. Somewhere, there is a mistranslation. What am I missing in the MT5 conversion, relative to the MT4 code? What am
MT4/MT5 conversion, what is wrong with the code?
I'm attempting to convert the indicator below from MT4/MT5. Most of the MT5 I'm sure is correct, but something is wrong. The MT4 file below is how the MT5 should work; why does the MT5 file plot incorrectly and generate a zero divide error? Thanks
Histogram won't plot?
