I have also thought on same lines. I have been trying to see if we can avoid the "fake calls" if one may call it by the Gann indicator using MACD and EMA Crossover techniques.
For example: If Gann says Short at 5023....but the short term EMA is moving above the long one and MACD also shows and upmove then its better to avoid the shot.
PS: EMA is obviously a lagging indicator but people do use it for intra day trading.
Another way out can be by watching the price behaviours near the pivots.
Suggestions plz??
