Strange MT4 iMA() problem

I use testing mode to improve my EA today,but I met a very strange problem about iMA() function,so I made a test code,it's very simple,just one line:

int init()
{
Print(iMA(NULL,10080,6,0,MODE_EMA,PRICE_CLOSE,0)+" ");
}

In testing mode this code just print "0.00000000",but if I changed timeframe to smaller values,then works fine.Also if I attach this EA to chart directly,it's works fine to,so is this a bug of MT4 testing mode?

In the Strategy Tester you only have access to a limited history prior to the start date, you probably don't have access to 6 weeks of data prior to your start date.
20 pips a day isn't too much to ask . . .

Weekly isn't available in backtester ... so I am not sure if even on a smaller TF it can check an MA on the weekly.

The limit is 1'000 bars back (from the start date) if I remember right.

The Strategy Tester can't run on W1 or MN1 but those timeframes are still modelled correctly . . . as far as I am aware.

Yes this was the point I wasn't sure ...

Though I never had issue by calling weekly/monthly in any strategy i've coded.

It's not really your mistake it's just a limitation you need to be aware of. There are other limitations of the Strategy Tester, have a read of this: Testing Features and Limits in MetaTrader 4
