Any know if it is posible to programe an indicator which allows multiple timeframes ( to add for example 3 indicators in same chart Macd for example) And for example looks at weekly daily and hour 4 timeframes ?


Sailor

its possible and even easy once you get the hang of making a basic expert from scratch. when your typing the code in the editor it will even tell you where to add the int timeframe which sets the mins for the pair. 240 mins for 4 hours etc.

I was thinking of an indicator and not an expert :-)

above is original code i thought i could just change this :

MACDLineBuffer[i] = iMA(NULL,0,FastMAPeriod,0,MODE_EMA,PRICE_CLOSE,i) - iMA(NULL,0,SlowMAPeriod,0,MODE_EMA,PRICE_CLOSE,i);
SignalLineBuffer[i] = alpha*MACDLineBuffer[i] + alpha_1*SignalLineBuffer[i+1];
HistogramBuffer[i] = MACDLineBuffer[i] - SignalLineBuffer[i];


any who can help me please

I am not programmer but I intested this one in the beginning of the code:

Zero is for current timeframe (anycurrent according to the chart.

And then changed the line of the code on to this one:

It means as Codersgurusaid, after NULL should be timeframe. Zero (0) is current. So I inserted my "Per" (see above) instead of this "0".

Indicator is attached.

First macd_1.gif is 3 timeframes: M30, H1 and H4 on H1 chart using this new indicator.

And next two images is M30 and H4 timeframe (and chart) with normal MACD (just to compare).

May be I am not right. It is just my attempt.

And an other image:

GBPUSD H1 Chart with e MACD indicators inserted:
for USDJPY, EURUSD and USDCHF.

So just 1 chart instead of 3.

Thank u very much digital :-) looks ok.... being able to customize period like this is very very nice should be standard in mt4 platform :-)

I think it is really good idea to confirm the enters by different timeframes and pairs movements.
