Hi, I am new to MQL4 programming and have a question. I am currently writing a EA. I would like to change colour of those candlestick when it meets my preset criteria. It will be fine too if it can mark an "Errow" or "Check" sign above or below the candlestick. I wonder is it possible? Can anyone help me? Thanks.

Help with EA to plot Moving average on screen

Hi, I am trying to learn how to program MT4 and cannot figure out how to plot a moving average on the screen. I can get all the other lines and stuff I want, but no moving average.

Can anyone point me to a sample code?

Thanks in advance for your help.

 

Moving average is standard indicator in Metatrader.

So, find this indicator here

and attach to the chart.

Nope, you misunderstood my question. I know how to attach an indicator, no problems there. I need the code to call the indicator from within an EA so that when I load my ea, it will automatically draw the indicator on my screen.

Hope I am clear this time around?

An example of a code which plot 2 MAs on chart:

ExtCountedBars=IndicatorCounted();

if (ExtCountedBars<0) return(-1);

if (ExtCountedBars>0) ExtCountedBars--;

int pos=Bars-ExtCountedBars-1;

while(pos>=0)

{

ExtMapBuffer1[pos] = iMA(Symbol(),0,MAslow_period,MAslow_shift,MAslow_type,MAslow_price,pos);

ExtMapBuffer2[pos] = iMA(Symbol(),0,MAfast_period,MAfast_shift,MAfast_type,MAfast_price,pos);

pos--;

}

Hope that helps.

I was wondering if anyone could help me make this EA increase lots as the account grew.. So it would use a percentage instead of fixed lots. Or just double up everytime the account would double.. Thanks in advance

Perfect. Exactly what I needed. Thank you, FerruFx!

 

toolbars disappearing.

Does anyone know why my toolbars disappear every time I shutdown MT4? I have to go through and reload the toolbars when I turn MT back on....

 

compile problem

Perhaps you can help me.

Sometimes when I compile a new indicator, MT4 decides to compile most of my indicators but not all of them. Some of my indicators do NOT appear in the Navigator window when this happens so I can't drag them onto a chart. Do you have any idea why this may happen?

I have to move some indicators into a different folder to get all of my indicators that start with "_TRO_" to compile and appear in the Navigator window. Could the "_" in front of the name be causing the problem?
