Too much slippage and delay for auto-trading, especially in a fast-moving market where scalps average around a point or so. I also notice a delay between the signal posting on C2 and it hitting my brokerage, which makes things even worse in a fast market. I've also noticed several occassions in which a very profitable trade ends up near zero or in the red, due to the vendor not locking in profits with a floating stop (especially true with his smaller quantity trades). Also, my actual fill prices are not reflected on C2 even when I use the "overlay" feature... rendering it mostly useless. This could be a very good system, with a few enhancements.
