The only way I know how to let my winners run is when I know it's a trending day... But lately I notice something else that might help out other traders... What I notice is when my profit target (2points) gets hit real quick, usually the market will run much farther.. So now when I see the market get to my profit target quickly, I just move my profit target up so I could squeeze more profit out of the trade.... That's one strategy I notice lately for letting your winners run.. But there's a second thing I notice lately that I could use to let my winners run.. When price comes real close to your profit target(I use a 2point target) and reverse... and price starts to slow down and take forever.. And then finally price reverses back to your profit target and give you a win.. This price action right here is an indication that price will most likely go much farther... I hope this information helps someone.. Signing off..
