Back testing EA with moving average.

 
The moving average only goes back so far. I have an EA that uses moving averages as one of many signals. The problem I am running into is that I can't back test further than the moving average goes. Are there any moving average indicators that go back as far as the time chart goes?
 

there is no such thing, moving average is a calculation of the price

 

TBN, be aware that indicator processing is quite different from EA processing.

e.g.

Indicator - it is expected that you will back-calculate indicator values before the bar of the first start call.
EA - it is impossible(*) to generate trades before first bar of first start call.

Indicator - IndicatorCounted() allows you to back-calculate bars-before-now on each tick entry.
EA - IndicatorCounted() always -1.

Note that the tester spoofs Server Time as it passes in tick information generated from historical information.

(*) If anyone DOES know how to do this, please let me know. I'm prepared to pay mega-bucks for this knowledge.

 
What ever the longest period the EA uses, make sure you have at least that many bars.
