I will admit, the only scalpers I have come across are trading treasuries.
The concept of scalping a volatile contract is mind boggling to me. I wouldn't even know what to look for.
My thoughts are that if you wait for a turn, you get a bad fill. If you try to get a short term turning point, you are going to give a wide stop.
Care to explain how this is executed in thin/volatile markets? I'm interested.
Simply, definition of "bad fill" in volatile markets is slightly different.
Slippage of 1 or even 2-3 ticks is also no biggie for CL traders (I trade 6E, but know a few successful CL scalpers/day traders). One lady, who's great in scalping CL, I once witnessed myself (we were on Skype with her), entered into the news, got 15 ticks of slippage against her on the entry, but still made 20 ticks of profit the next minute.
Targets are also typically wider, as well as the "wiggle room" allowed.
What I look for is momentum. Basically very primitive breakout trading. You enter on a stop order and if trade goes in your favor, great, if not, loss is small.
It would kill most in fixed income I guess, except the cases of "real" serious breakouts, which are relatively rare.
But in volatile markets even fake breakout very often allows you to at least move the stop-loss to break-even and enjoy the risk-free opportunity. And if the breakout fails immediately it's usually good trade in the opposite direction.
So shortly, all strategy is built around price levels. Probably can be done without charts, by using the DOM, T&S and simple numbers of H/L's of last few hours/days too if one prefers those tools for some reason.
But charts give me a good visual "feel" for market. Probably because my background is psychology, not physics or math.
P. S. I have posted links to my blog in this thread with examples of real trades and stop is not necessarily wide, when trading momentum, just takes some skill (as everywhere) to pick those entries, where momentum is most likely to explode.
