Got in on that early bull move, so I'm funnin with Fib. Here's one, see if you like it. When the market has moved in your favor the distance of your initial stop, reset the stop to 61.8% of the move from the current price to stop. For instance, if your initial stop was 2 pts, and you now have a 2 pt profit, that would be 61.8% of 4 pts or approx 2.5, so your new stop would be 2.5 below current price. Any good? What is the math formula for this? Why 61.8 %?
Why 61.8%? You need to read a bit about Fibonacci series or the Golden Ratio (do a Google search for that) to understand why. I use 61.8 % FR to enter on a pullback within the first 30 min bar and then you get your initial stop-loss automatically which for ES is (1-0.618)*BAR LENGTH+0.25= 0.382*BAR LENGTH+0.25, but adjusting it the way you do that would be a bit too much work for me. But that's just me...
