Ok - below is a little more clarification on that specific test: short entry when RSI(2) is greater than 95 close the short when RSI(2) falls below 50 long entry when RSI(2) is less 5 close the long when RSI(2) goes above 50 The strategy compounds, starting with a fictious account net worth of 10,000. Each position taken would be for current account net worth X 2. I have to agree with you it does look like a very simple stategy that has very tasty returns. Marc - have you guys thought about other indicators like %R and CCI for extremes ? and any conclusions ?
