Hello,
All position management functions are included already in the
Custom Portfolio Backtester interface.
Read this VERY carefully:
http://www.amibroker.com/guide/a_custombacktest.html
On every bar you have access to currently open position list (for entire portfolio),
each having all stats available. You can access system (porfolio)-level
stats on bar-by-bar basis. You can even go through closed trade
list also on every bar.
The flexibility with custom backtester is ENDLESS.
In fact AmiBroker Custom Backtester functions
are WAY SUPERIOR to wealth-lab for one and foremost
reason - they truly operate on PORTFOLIO-LEVEL.
Regular WL position reporting function will report positions
for SINGLE (current) security.
To report all positions for all securities at bar-by-bar basis it requires additional code wrestling
that slows down to the crawl.
Best regards,
Tomasz Janeczko
