The answer lies in understanding how the indicator paints different colors. Do you know what a buffer is? If an indicator wants to display multiple colors, it has to use different buffers. If you can figure out which buffer relates to the color ...

This may be what you're looking for. It's worth reading the whole thread, my last update was in post #28 and others have taken up the banner and made additional adjustments after that.

Here you go — Just Google something like forex system 100 pips and check the paid adword listings. Good stuff.

Correct. Use a global variable or share data via files. I'd recommend NOT relying on the comment field as some MT brokers have been known to clear out/modify the comment field during swap roll.

If I correctly recall the inner workings of DDE, the last app to register itself as "MT4" is the one you're going to be pulling data from. My guess is that the functionality you're looking for is beyond what you can get with DDE. You might be ...

If NormalizeDouble(StrToDouble(str),4) is returning 1.406, that IS 1.4060. That's why I'm saying the NormalizeDouble isn't your problem (provided you're trading on a pair that uses four decimal places, and I'm betting you're trading the euro). Is ...

Mobile doesn't support custom indicators.

Your problem isn't with NormalizeDouble, look elsewhere. Error 129 is invalid price, right? (I'd check, but on blackberry). I'm guessing that your submitting on the wrong side of market.

Most. Asked. Question. Ever. The answer is you can't. In the future, please use search.

Are you specifying a directory that you have write permissions to? Aside from that (which is just a guess) I can't really help you much more from my end.

Pm sent.

Not something that can be done with default functionality. You're looking at dll calls to get it done. I think the plot news indicator does this, check the code to get an idea of what's involved. Would check for you, but on blackberry.

Just eyeballing it, the code looks fine. I'm guessing that there just aren't that many instances where an ema changes by more than 25 pips in one bar. Try testing with a smaller value (not larger like the 2000 you're using). Also... outputting ...

PM sent, but just know I'm not the cheapest guy on the block.

First thing that comes to mind is that you're checking for the crossover on the current bar. This means you can get a cross, then price retracts and the cross goes away. You've already drawn the arrow, so there it stays.

What's your backtest quality? Are you recalculating pip values or utilizing previously generated ticks?

I'll touch on a couple different issues, hopefully some of this information is helpful. First, regarding global variables... Global variables store values as doubles, I'm guessing you've figured that out. The good news is that there's no problem ...

That's an odd question, but I'll confirm. Since your EA runs on your computer, it won't work when your computer is off.

Coded for option #2 (previous close vs current bar) based on what I could glean from your code. Only the first alert condition on any bar will fire an actual alert. I tried to be verbose with my comments to help you understand what's going on. I ...
