ok ..I can't show it ..but you can run these curves on 30 min data ..even less ..if you want ..but I find 30 best ...unfortunatly I can only show you a dialy ..
when the price get up near the 3rd deviation ..( the red ) you can look to fade ..as price will head back towards the center of the curve ..I use candles and divergence to help get an entry when it aproaches these levels ..
for the curve to develop the price must rotate from high to low ...natural process ..as i said trading in the top or bottom of the curve give the best risk reward atvantage ..
I'm not great at explaining ..but thats the generall idear ..
I sold spi today using a 30 min curve on it ..up at 90 sucessfully ..and earlier bought 65 ..so if you know how to use it and you like it ..it's fun .
I could explain more but it gets complex and mabye not right on this medium .
