I have just replied to MetalTrader under this Sierra Thread and did not want it to be under DDT discussion.
He was specifically addressing the way we quote prices all in on the Rithmic+Sierra discussion.
PM with any questions about optimusfutures (800) 771-6748 (561) 367 8686. THERE IS A SUBSTANTIAL RISK OF LOSS IN FUTURES TRADING.
I use SC and have no problems with it, and so would support it 100%.
Its cheap, stable, reliable etc;
(my only criticism is that I cannot effectively load equities (for most non USA markets), as its futures and USA focused)
However....as a note on portfolio backtesting....there seem to be very few true portfolio back testing systems available. While some systems claim they can do it, they may just be running through whats is effectively a daily scan and taking all the signals.
A true portfolio system allows you to have rules for which signals to take based on the exisiting portfolio and the days signals as they are given. Otherwise you are never taking into consideration such things as portfolio concentration and correlation issues. You need to be able to have rules for which signals to ignore if the portfolio is full, or which existing positions to replace.
In reality you might have twenty long positions on - lets say your signals tell you to buy another twenty longs. Do you have the cash to do this, do you take them all even though your market exposure doubles? What is your over all exposure? how correlated are you?
For true portfolio testing this needs to be taken into consideration.

Thanks: 227 given,
I had not envisioned such a scenario to backtest. I see the value and understand. The backtesting that I want to perform, and currently do in Prodigio, is as described above. It seems that MC can tackle that well, but I seek confirmation...
Conceptually, Prodigio is pretty cool, dragging and dropping indicators, connecting with arrows, including "if" "and" "or" statements and the like and backtesting against a universe of stocks over a year or greater is worthwhile for me. It's a little quirky at times, but has promise (and I think limitations) with no languge for the user to input.
Thanks much! From what I've read, SC is not horsing-around and constantly improving. I have more to read. Thanks again.

Make them about how you trade, not how much money you make. 4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance. 5) Where to start as a trader?
