I just had an illuminating chat with Marcin, that
I'd like to pass on...
In my backtests, I noticed that I randomly got an
extra trade at the beginning of a data set.
Marcin found the problem to be because I had
checked the Pad & Align box in AA window.
The help files warn to use Pad & Align
judiciously as it is meant for data obtained from Foreign()
function.
Of course when I unchecked the Pad &
Align, the backtest results were what I expected them to be, without the extra
trade.
The implication is that when Backtest is run and
there are a lot of trades, the impact is probably not noticable. If you have
only a few trades, the the impact may be significant.
It seem that this is not a "fixable bug", as it is
not a bug at all, but a feature for a specific purpose and when it is misused
(as I misused it ) then a problem arises.
Marcin, thanks for your time.
