I'm trying to migrate some formulas I use to scan stocks from strategydesk to thinkorswim but I see its different in thinkorswim. I donīt find how to make scans of an EMA of a week, I want to know if the slope of the EMA of the week is positive, some idea.
This is the formula I currently use in stretegydesk:
(ExpMovingAverage[EMA,Close,26,0,W] > ExpMovingAverage[EMA,Close,26,0,W,1] )
AND (ExpMovingAverage[EMA,Close,26,0,W,1] > ExpMovingAverage[EMA,Close,26,0,W,2])
Thanks in advance
Tony, thank you very much, so SD will be a part of TOS? Thas great news. SD works great to do backtesting, its really easy to use, its not so great with graphics and the scans are kind of slow but gets the job done! I will check thinkscriptor.com
There's another thread here in this TOS forum where I mention this in more detail, just yesterday actually...
I heard about SD into TOS twice yesterday, once via email, and once over the phone later in the day... Here's the email:
We do have plan to integrate the backtesting and scanning functionality of Strategy Desk into Think or Swim, and eventually sunset the Strategy Desk platform itself. We have a tenative date of early 2013 for this. Beyond Prodigio, we don't have anything else at the moment.
The scans are a bit slow, but certainly faster than their Prodigio... Hope this info helps.
The programming is very fast once you make the conversion in thinking from script to visual. I just write out the formula and start dropping logic boxes on the screen and wiring them up in the same flow as the math would go. It takes a little time to make the conversion in thinking however it gets very fast once the light-bulb lights up and you see how easy it is.

Thanks: 227 given,
Sabine, thanks for chiming-in, and for supplying that Prodigio strategy.
I was most excited to learn that TDA / TOS got Prodgio, and used it a fair amount in my TOS paper account about a year ago. I just had it added to my live account a few days ago, after not using it for several months. It has improved, in some ways.
I ran a previously created strat backtest, a simple RSI cross entry, and RSI cross exit, and it took about 1 hour to complete (500 symbols, daily bars 1 year duration). I will try again now as maybe the system was having issues...
Is that normal, that long of a wait for backtesting results?
Just started the same backtest now, at 12:10 PT. Hope it's faster....
