Now here's an order I could be interested in from time to time. It's a trailing limit order. For instance, you just know you want to buy ten points below the highest high.
I want 1 of those myself, limit order to track up the 6sma Envelope, so a few pips less than 6sma on a M1 chart. Take every pull back in a strong trend, take some pips then repeat. Chart example, so towards the lower white envelope on this move. I'll be moving it manually, and resetting up when used sadly.
