It has been called to my attention that, under certain circumstances, C2 is overly generous in the way it determines Buying Power for stock systems. Tonight, C2 will install some new software which will correct Buying Power / Margin Usage calculations. Not all systems will be affected. However, if you suspect your system is using "too much" buying power, than I recommend you adjust positions as necessary in order to avoid margin calls.

Good the hear, Matt. I’ve seen it as well, although I’ve not taken advantage of the loose haircut controls.
