That's a large stop for a day trader - especially if it's hit. Is this more like a disaster stop or do you actually take a 10 point stop-out?
If you have a high win percentage it should/could work, but make sure you get out before it's hit if you find out your trade isn't working out as planned. With 2 of those in a row you need a 'miracle' just to break-even on the day.
Do you have a daily loss limit also? 30 points per contract is a fairly large drawdown, IMO.
I'm using 10 point initial stops, too, but they're more like disaster stops and I usually don't take a full stop. I will also breakeven my entry or tighten my stop as soon as the trade goes well in my favor. Rationale being I don't want a winner to turn into a (big) loss and figuring I could always re-enter if stopped and the original trade idea is valid. This can be challenging in a fast market, but as a general principle I try to do it.
The reason I'm using such wide stops now is because I usually have a good grip of where the market is going - broadly. But my entries aren't always the best, i.e., I can be a bit early at times and the market may have another 5 points to go before turning. And I've lost count of how many times my 'read' was correct and I got stopped out for multiple 3 point hits before the market left the station without me (or with me in a 6-9 point drawdown). So, wider stops have been beneficial to me, although I am taking on a bit more initial risk too.
Personally, I believe the solution is to clean up and improve my entries. There truly is areas on a daily basis where you actually can enter with a 3-5 point stop and it will never get hit. The key then is of course to be very selective and only enter at those key areas. And avoid entering trades where 10 point stop is required.
No easy answers here.
Sorry if I sound like I'm preaching, but it's something I've been thinking a bit about myself lately.
