Try replaceing this line
limit=Bars-counted_bars;
with this :
limit=MathMin(MathMax(Bars-counted_bars,2*TimeFrame/Period()),Bars-1);

Hi Mladen,
I'm having trouble coding this EA since the entry rules are something I've never done before.
For example, in this trade, it's simple to write the entry rule since the green and red arrow appear at the same time. So on the open of next candle, we take a short position.
But, in this next example, I first get the green arrow without a red arrow. So I don't take the trade until the red arrow appears. On top of that, all candles that are after that green arrow and before that red arrow must be UP ones since otherwise this is not a valid trade.
How the hell do I code this specific rule? I know how to code it for current candle, but I don't know how to specify these conditions. Any help would be great!

Why don't you copy the logical conditions from the code that is creating those arrows?

I'm not quite sure I understand what you're saying...
What I'm trying to find out is how in my buy or sell conditions I make the EA understand that when the red arrow appears (that is trigger) the condition is that there must have been a green arrow before and that all the candles that follow that arrow must be UP or DOWN depending on what is needed. But I don't know when that green arrow would have appeared...

Hi Jason2005,
The Red and Green Arrows are values in the buffers of your indicator....not your EA....
Use iCustom in your EA to call your indicator values in the buffers...and then use them for your trading strategy.
There are many good posts here in this forum about how to use iCustom in your EA...
In the meantime...if you attach your indicators here...someone may be able to help show you which indicator buffers you can use in your iCustom statements.
Hope this helps,
Robert
