Nas100 Market Open Short

Took a short on Nas100 at market open yesterday. Price was above the pre market low, as well as coming off the top of a strong Daily pennant formation, but unfortunately this one went against me. I got stopped out at 400 pips in a loss but followed my risk management properly. I've seen from backtesting that some draw down is expected, and I'm not trying to hide my losses because they happen to. Let's see what today has in store, I'm still sticking with my short bias
