It looks like a pretty good system but it is hard to tell.
Keep in mind that the Sharpe Ratio reported by TradeStation is not correct.
I would first try trading a fixed dollar size over the period, adjusting the number of shares appropriately:
NumSh = 100000 / Close;
This should result in a more linear equity curve and get rid of the complications of the price changing so much and the number of shares changing. This will test the underlying system idea better.
Then plot the equity curve vs. time and see if you still get the dead periods. (I plot of equity vs. trades can be misleading.)
If so, figure out what is happening in the market during those periods. You may be able to see something you can fix.
