I'm getting close to finishing "Version 2.0" of my market bots, and along the way I've made a few discoveries that I've been able to incorporate into the soon-to-be-obsolete bots that are are currently operating. Today I made an additional modification (now up to bot 13_20) that both increases the average stock market returns and reduces the number of trades required.
Market conditions are pretty much unchanged since my first bots began operating. Internals are on the bullish side of neutral, and the long-term trend remains positive. Since closing at an all-time-high of 1709 on August 2nd, the S&P 500 index has fallen 3%, which doesn't yet count as an official correction in my book.
