Re: [amibroker] Re: Different PositionSize Values displayed in CBI and AA report, AmiBroker Email List Archive

As Tomasz said, save those values using temporary variables:

VarSet("Entry"+trade.Symbol, trade.GetEntryValue());

and then later retrieve with VarGet.

Would be kinda nice though if there were some spare variables in the
Trade object, to keep it all nice and object-oriented.
