Problem makes me crazy

Please help me with this one, i am desperate and my bloodpresure is going wild of this. I have attached an ema crossover indicator which puts an arrow when (in this example) an ema1 and an ema3 are crossing. In realtime an arrow is put nicely on top or below the candle in which period the ema crosses (on candle close).

So far so good, this works but after some time some of the arrows disapear.

Why ? I don't have any idea but this really frustrates my backtesting.

Can anybody please look at this indicator what is going on. It's a small basic indicator but unfortunately I am not a programmer and I am stuck for the moment.

Attached: a screen shot of a chart with missing arrows. I have manually put the big arrows on screen to show you the missing arrows. In de indicator windows the crossover of an ema1 and ema3 to show that a couple of arrows are missing.

Thanks a lot.

Try this. I think I found the issue but I haven't tested it.

Magnumfreak, you are fast and a GENIUS !

I have tested one week of data and all the arrows are there. In the old indicator the arrows did appear on screen but after a while went away. When I did attach the indicator again the arrows still did not appear. That's why I know it is allright now, GREAT !

I have downloaded a couple of emacross indicators, they have all the same problem, this might be very well the only one working.

Maybe I will send you a nice magnum icecream, THANKS A LOT !

Glad to help. Keeps me busy when the markets are slow.
