If there are not enough bars then expert tab and journal has an error there, look through them for hints. Does the EA compile? Do you have the necessary timeframes available? Open separate charts for those TF's and see if it helps.

No visible errors, unfortunately I can't test it currently on a platform.
But try the one attached if it changes anything.

Are there no error messages in Journal and Ea tab?

How many bars do you have then for respective symbols? In MT point the cursor at the chart name tab below, then the number of bars will pop up. I think the EA will print the "not enough bars" message on the chart as well.

Interesting.

There are enough bars, so we can rule it out.

The problem seems to be in spread calculation, somehow Point value is returned as zero, it seems.

Try the next version attached.

Hmm, yeah, the error is somewhere else... Now it shows array out of range error.

And you have trouble with only micro accounts.

Can you check your all 3 platforms and see what builds they are? In mt click Help->About and the build numbers, probably they are the same but lets be sure.

Try this one.

It looks like this is a multi-market strategy. If some of the additional market indicators require more than 100 bars, we have to make MT loading them.

Does yuor symbol is EURUSDc?

In that case, the strategy will not load the data because it searches for EURUSD.

This can be the reason it shows that cannot load bars.

We have in the EA:

   strategy.Slot[1].IndicatorName    = "Moving Average";
   strategy.Slot[1].SlotType         = SlotTypes_OpenFilter;
   strategy.Slot[1].SignalShift      = 0;
   strategy.Slot[1].SignalRepeat     = 0;
   strategy.Slot[1].IndicatorPeriod  = DataPeriod_H1;
   strategy.Slot[1].IndicatorSymbol  = "EURUSD";
   strategy.Slot[1].LogicalGroup     = "A";
   strategy.Slot[1].IndicatorPointer = indicatorManager.CreateIndicator("Moving Average", SlotTypes_OpenFilter);

Please search for "EURUSD" and replace it with EURUSDc.

EDIT:

The strategy requires more market also. Please correct the other symbols in the expert.

FSB Pro includes the exact symbol names in the EA.

The most reliable way is to import the data from the broker you are going to trade. In your case, the symbols must be EURUSDc, GBPUSDc... and to use these when creating strategies.

FSB Pro may complain of the symbol name because it may require six capital letters. Set them as "CFD" in such a case.
