As far as I remember, professionals give more room to trade at the start (wider stop), and as trend matures, they start tightening the trailing stop (cause all trends eventually end).
Rohan, seems you have read about 3ATR trailing stop approach and using them. Great that atleast you have some approach of trailing stops. But Bhai.. it is important to understand the psychological impact of such wide stops. If you can't handle that impact, then probably u shd use some other trailing stop approach.
Give a shot to Parabolic SAR which automatically takes care of tightening the stops as trend matures.
Happy Trading
