I know I've been struggling to describe this system to you guys, partly because it's MUCH SIMPLER than it sounds!

Here's one final attempt.

It's a simple stop-and-reverse.

It has one parameter X%, which is a trailing stop.

You enter a long position with a trailing stop. When the trailing stop is hit, you reverse and go short with the same trailing stop. When the short stop is hit, you go long. Rinse and repeat.

You mark the highest point of the long trade as the swing high and the lowest point of the short trade as the swing low.

The only catch is that you don't do this with a stop order but on the close of each 15m bar. If you do it with a stop order you will get stopped out much too often.

Now add a profit target and a (looser) real stop loss and you are set.
