Why not ask the wonderful *cough* staff at eSignal, you might get an answer in a year or two. No but seriously, I look at price, and I trade price. I don't trade based off an indicator specifically to determine entry. I look at price to determine my entry, and I use other indicators, like moving averages and S&R to determine my R/R and such.
i am a micro-scalper learning&trading , trying to get whatever chart stuff i need setup. I use pretty much just the 1min chart. do you use the open book and level 2 for print and etc a lot. what kind of stocks are you trading these day?
The one minute time frame is useless in trading (great for brokers raking in commissions). Teen age boys getting their first jump is usually a done deal within a one-minute time frame, but for trading futures like ES the best time frame for a daytrader is the 5 minute. When daytrading play with the same deck the others are using. Have fun today.
parabolic SARs can be helpful when you integrate it with other indicators. They can clue you in on entry/exits.
