Terry,
actually I dont know how function equity() can help me to calculate
the number of shares per position that has been bougth while
backtesting. Documentation on this is, as for many other functions,
very poor and there are no examples at all for the needs I have on
this specific problem.
While I find Amibroker is a very impressive tool and has sometimes
surprisingly useful functions, I cannot understand why such a
fundamental information like "TradeSize" is not easily available
like other arrays p.e. buyprice, sellprice etc.
I am spending hours and hours trying this and that for 3 days
already and I dreamt about it last night. Sometimes its just
frustrating and I guess to use a more expensive product with a
better documentation would save me a lot of nerves and time.
