There is an entry method for day-trading that can be used for both mean reversion and trend-following. This is because a trend trade intra-day may be a reversion on the daily. However, many would likely view this as a trend-following entry method, but they are not likely looking at the 'big picture'. Having discussed system development and strategies with traders and firms for quite sometime, I have yet to try to explain that we are trying to capture both RTM and Trend-Following in the same algorithm, but allow the market to guide us as to which to implement. We have designed strategies that vary entry methods based on where the market opens as well as other conditions (such as daily price patterns). Therefore, we are combining both "reversion to the mean" strategies with "trend following" strategies into a single algorithm for entry. This makes the systems much more diverse than just trading either 'mean reversion' or 'trend-following'. Are there any others out there that develop systems in a similar fashion?
