EA DTosc ... sorry!

[cello23]

Hello everybody,

Sorry but i m newbie...
I would like to create a simple EA based indicator Dtosc:
BUY cross <30
SELL cross >70

I start with indicator but I can't turn it into an EA.
Please, can someone kindly show me what are the first steps?

This is wrong:
if (SD > SK )
{
Opn_B=true;
}
if (SD < SK)
{
Opn_S=true;
}

I USED THIS INDICATOR----

Hi. I have a strange query. I am adding the indicator code to editor and then adding the indicator to the chart. I can see the chart has the indicator window but there are no lines drawing. Do you know why this would be? So I even see the indicator values on the top left of the indicator window below the price chart but no lines are actually plotting.

   Just get the value(s) of the indicator(s) into the EA and do what you want with it.
   You should encapsulate your iCustom calls to make your code self-documenting.
