You don't need to have your reward greater than your risk to make money... The only think you need is a edge AND an adequate money management. I use to do scalping (1 tick only) in a prop trading firm and no one had a reward > risk, you will often risk 2/3 ticks to win 1, but because we had an edge, our % win was very high and we end up being positive. Also look at insurance companies, they have very bad risk (paying you in case something happens) /reward (the annuity you pay) ratio but still make money because they have an edge (knowing the probability that you will have an accident). The point predictor is trying to make is that if you have an edge (like you good at drawing trendlines) but don't know where to stop and exit, using a fix ratio as described can eventually help you. Now you need your edge to be good enough to compensate for slippage and commissions.

thanks, a pity it isn't OHLC data

That's rangebar, not tickcharts
