[amibroker] BUY and SHORT at the same Bar?

[dirk schreiber]

hello group,   i am trying to run a pair trading strategy through AB's backtester and have run into some problems:   - how do i tell the backtester to buy one ticker and sell another ticker at the same bar?   here is what i thought would be a good idea: i use AddToComposite() to build an artificial pair ticker. C is assigned with the pair ratio, H and L hold the values of the close of ticker1 and ticker2 respectively. now if ratio does <formula> Buy ticker1 and Sell ticker2, this obviously does not work as you cannot go long and short at the same time. or is there a workaround? referencing Foreign() or playing around with Buyprice() did not work either, the backtester only takes the long signals.   i would be grateful for some ideas,   dirk Please note that this group is for discussion between users only.
