Why I am having problems running RenkoRangeBarsV1.2 EA

Hi,

Could somebody please assist me as to the reason why two different brokers react differently when running RenkoRangeBarsV1.2 EA on the MT4 platforms

When I put the EA on FXDD MT4 platform it quickly consumes the computers resources and memory and I have to switch if off !

If I use exactly the same EA but with PepperStone MT4 platform - I have no problems at all.

What could be possible happened to cause the difference ???

Thanks
