Hi Liam, did you take into consideration the much wider stops you need to play GY off small TFs? Spread is poo with the SB firms too..I can get 2 pip spread off dbfx/fxcm but isnt IG 7 (iirc)? All that said it can be (imho) a great play GY.
In all honesty mate, no. All I did was draw 4 lines, top of the range, bottom of the range and then the distance of the range in each direction. When it breaks it usually goes 1:1 before coming back and if it stops you out and breaks the other way it's usually safe to trade the break in the other direction to end the morning break even. The danger is whipsaws so best to take two trades max (1 in each direction). This is all only over the last month though!
