HB: I looked at that and just looked
again.  They sure do not look like percentages to me (47.79, 197,51,-67,
etc) (this from a backtest I just clicked on).  Plus, the thing that says “Individual
Backtest”, when you click this you get the OLD backtester running but
with NEW column outputs??  Is that correct?  I was thinking the third
choice, which says “Old (v4.4) Backtester” was the “REAL OLD”
backtester.  Why do you guys think the third column from the end is in
percent?  Or perhaps there is a preference I do not know about that makes
it be in percent and I have mine in default $/bar.  Comment?

Ken,





 





Profit/bar in the new backtester is in $ amounts.







 





Profit/bar in the old backtester is in % and is the 3rd
to last column in the results table (before MAE/MFE).

<font size=2

continue to use the OLD (v4.4) backtester.

As I can not "see" this statistic
anywhere, can you lead me by the hand
to show me where you get this statistic
(profit/bar in %) and what
settings you make to ensure it appears.

I see a "Profit/bar" column in the new
backtester output but it does not
seem to be in percent.

What am I missing, please.

Trade list for old backtester also gives
profit/bar in % which the new
backtester does not.  I use this a lot so
it's one of the main reasons
I use it.
