My strategy is based on 15 min time frame. It will open a buy trade when TVS of 6 and 3 time period will be in positive and there will also be EMA 8 and EMA 34 crossover in buy trend. That is when EMA 8 will cross EMA 34 above and vice versa for sell trade when TVS 6 and TVS 9 will be in negative with that EMA 8 will cross EMA 34 below.
