Hi dah7,
I just spent some time over at the TS forums to check... I have yet to find any solid free MP indicator for TS. There are two other versions available but in my opinion needs serious work.
The only MP indicator that I came across that got my interested was a commercial indicator available here:
Market Profile, Price Distribution & Value Area indicator systems for TradeStation
I shot them an email requesting a free trial so I will keep you posted on how that goes. If you happen to come across any free versions, please let us know. Thanks
