I’m sure Ed mentioned this, but my testing this past week brought out to me how important it can be to check “Allow Settings To Adjust Trade Size” in Account Settings…

The following snag shows 3 sequential situations, all with the same set of portfolios in an account in the month of July.

#1 is trading with neither the “Maximum Exposure % per Symbol” or the “Allow Settings…” checked.
To the right are the graphs and the historical positions, which shows a lot of trades with QTY% quite high in the first run.

#2 shows the same setup with the “Max exposure” now checked and set for 30%. Notice to the right that ALL the trades that had QTY% greater than 30% are DROPPED!

#3 shows that if you additionally check the “Allow settings…” box those large QTY% trades are now taken and scaled back to 30%. This has the additional effect of allowing some very small trades to be added (could be good or bad?).

I wanted to share with everyone what a large effect these 2 boxes and their interaction can have on any portfolio, and how it can affect the outcome of a portfolio you may be building by showing the difference in the graphs for the 3 examples.

Mark

Mark,

The "maximum Exposure" setting originally worked (incorrectly) as you describe here and then had been fixed to work as you expected. However, it is now back to the original state again.

Nirvana, please fix this again!

Thank you,
Jim Thorpe

Ooops, if I had Actually READ Mark's post, it would have helped!

Another possible solution is to change the "Allow Reduction" input to its mirror image - "Ignore trades that violate filters (don't reduce their size)". Default that to UNchecked.

This would allow the "natural expectation" of the user to be the default.

Jim,

Ah, that is likely the solution the "Allow Settings to reduce trade size". When that was added, it looks like it requires setting that checkbox for it to work as it had before. I had wondered why with this release, all of a sudden I was not getting any suggested trades! Thank you for pointing that out.
