alex, i went with ET & RSI...
extremely oversold... bounce back was on cards... and theortically, FUT's LOD was almost same as yesterday... (ignoring 4030 sneak)...
now, either enter long at 4000 with stop 3940 or go short at 4160 with stop 4200...
(require confirmations from indicators, etc at that particular time...)
also, visit this link..

below the two charts, there's this daily SCO value (no idea what it is, but previously, author had expained it was linked with RSI)...
observe the result for atleast 2 weeks, and i m sure you will be satisfied...
