Re: Equity Curve Analysis

I'll plug in the Sharpe Ratio. Thanks.

I failed to mention a few things:

The strategies are applied to intraday data.

This equity curve is based on trading two stocks, each using a different 
strategy. I matched stocks and strategies based on a high RR, low standard 
error, and relative negative covariance. I multiplied all my RR's by 1000 
because I wanted to see whole numbers. Also, I didn't account for any 
slippage, which is a weakness. I hope that 900+ trades in four years of 
changing markets is statistically significant, but perhaps it's not.

Here's another catch: These strategies are not super robust: if I apply the 
same strategies to different stock combinations, I can get unsatisfactory 
results. You could say that each market is a different animal, and you come 
up with a strategy for that animal, but these beasts are known to change 
into something else.
