The DJI has been pretty wild so, I use it as an example. Figures shown here are not my own. I only use the figures to explain why it doesn't matter how you make your profits. HFT's will do similar things, so why can you not?
Well, I show the value of the ATR on the 3 min time frame as a way of making an exploit. I have to say that this is mainly for day traders with a lot of 'bottle'. So in the most recent scenario, I show how 403 points could have been made shorting. I other scenarios there are slight gains and some losses. No trading strategy could ever guarantee 100% gains.
I show a technique for deciding on an entry point (long or short).
Exit points can be managed based on the or trailing down and allowing price movement to stop you out.
Is this about luck? I don't think so. Luck is about rolling dice. This is a calculated logical strategy - so your not throwing money randomly in the market. The use of the ATR, and retracement criteria at the start of the trend change means no die are being rolled here. This methodology is about readiness and positioning.
