You have OnCalculate() handler there, it receives High, Low, Close and Open arrays as parameters (just read the helpfile for the exact details). Then in the code you can use High[1] and High[2] the same as in MQL4. Just remember to convert the array to timeseries with ArraySetAsSeries(High, true) if you want the same order of the elements as in MQL4. If you want to execute it in the indicator then it’s easy.

I know there is a conversion mqh file for the timeseries, but how can you write in the MQL5 proper way the following ? If High[1]>High[2] ???? Dumb question i know, but although I am experienced in MQL4 I have found no information on how to do the umtost basic stuff in MQL5 Hope you will spare a 1 minute to answer that. thx Hi, just read your blog, was hoping you could answer a very very simple question.

You may want to wait for the MT5 do be out of beta testing. Perhaps, MetaQuotes will offer some more or less automatic tool for that.

That's why I had to use ArraySetAsSeries(Close, false); to properly convert and correlate close prices of the bars with the bars of the indicator.

I don't understand why they have made the default arrays non- time series (ie latest bar is rates_total). It seems more intuitive to write code with latest bar = shift 0. If you look at fai's excellent MQL4->MQL5 porting table in http://forum.mql4.com/, he suggests converting CLose[] etc using SetAsTimeSeries in OnCalculate. The other point is that MT5 already has iMA etc coded, but it's quite tricky to use these with the CopyBuffer command. The MACD example shows one approach. Nice coding.

You may be not noticing it because of the low timeframe, try D1. It adds two other lines shifted vertically by percentage value – one above the MA line, other – below MA line.
