I've been using this method for the last 3 months on my live account and it is very strong. You can even use it in the 1 minute charts to scalp for 5-10 pips.
For me, i now use this strategy on the 1 hour and 4 hour charts and I find it ridiculously strong.
Just like Big E, I enter the trade on the 4 hour chart once the TDI green crosses the red signal line and I just leave the trade overnight before I go to sleep.
One of the best feelings is waking up and seeing your mobile MT4 in the "blue" profit screen.
Use this stencil for your entries. Just line it up next to your TDI green line and if it matches the angle in the stencil go for it!
