I've used IB's trailing stops on es. Once you enter the stop, it trails, but it doesn't show you where the stop is. So it is difficult to judge exactly how flawlessly it is working.
profitably? Those doggone trailing stops. I trade because I want to be able to control my income. Once I enter the trailing stop, I know, you know, the whole world knows when the move has stalled, and I sit there like the powerless peon I am waiting for the pullback to trigger my stop.
I already have my profit, now the market has to move the distance of my stop for me to get it. Yes, the trade is profitable, but it would be more profitable just to pull the trigger when the move has ended.
Would have made more money today if I'd used a trailing stop instead of thinking I am so powerful that I alone know when the move has ended.
