Coding MACD / Laguerre Arrow Signal?? HELP

Coding help anyone? Is this even possible?

Basically, I'm trying to get an arrow signal (such as the ema crossover) for a Laguerre and MACD combo. It looks like there are some EA's that have already done this for the most current bar, but none that show arrows going back in time (for backtesting). Does anyone know how to do this? I've been messing around in MT4 code and I can't figure it out.

Once again, I'm trying to get an UP Signal Arrow when the MACD is above zero and the laguerre has crossed up from below .15 in the last 3 bars.
I need a DOWN Signal Arrow when the MACD is below zero and laguerre has crossed down from above the .75 in the last 3 bars.

Any help with this would be amazingly appreciated!

Thanks!

Anyone? Anyone? Bueller?

ANYTHING is possible, however, many of the programmers on here are very busy with other projects so keep trying until someone comes available.

Will do, thanks Magnum

I'll just keep calling for bueller when i hear crickets...

If anyone could just explain to me how the draw_arrow is actually called from the code, that would help a lot. I see this in the initiation section:

SetIndexStyle(0, DRAW_ARROW, EMPTY,3);
SetIndexArrow(0, 233);
SetIndexBuffer(0, CrossUp);
SetIndexStyle(1, DRAW_ARROW, EMPTY,3);
SetIndexArrow(1, 234);
SetIndexBuffer(1, CrossDown);


But I have NO IDEA how to call those indexes from the main function

Any ideas?

Nevermind that 2nd question, I figured it out
