Trade only significant trends. Such a trend has to have an underlying reason with a large potential for change. It must be an outlier -- Trend Sigma. We are trying to find those chances.

Try to get on the trend with a system that keeps losses in check. If a trend is there, it will survive the stop. If it doesn't survive, there is no trend. This part is the art of trading and it needs a system.

If a trade is far enough in the black, disconnect the entry system and hold the position with a stop near the original entry and switch to a system that allows for larger retracements.
