1. Cash is a property of the backtester
so bo.Cash gives you the available cash at each bar;
2. posize and poscore are properties of the signal object.
if you want to you can do all your selling/scaleout first, and use the
available cash to do what you need.
and use the bo.EntrerTrade or bo.ScaleTrade to do what you need.

Subject: [amibroker] Re: CBT: Scaled trades
Thanks mate, but forgot to mention: I use rotational mode in CBT
which seems to complicate matters due to the fact that scaling is
triggered by stock-specific variables (arrays) which relate to both
(current vs. required) PositionSize and (previous vs. new)
PositionScore.
I have been unable to determine:
1) how much cash is available for all ScaleIns at each bar
2) how to allocate this cash according to a specific "ScaleIn"-rule.
Support question, I suspect.
