I trade as if price is random. So far I'm really only comfortable doing this on a long term basis (eg. not intraday). Let's discuss methods of trading that don't involve prediction. I hear people say a lot "cut your losers short and let your winners run." When I trade, I can't do that because I don't know if a winner is going to keep being a winner nor do I know when a loser is going to turn around and become a winner, but I discuss my trading system in another thread. Does anyone have any concepts or ideas for non-predicting systems? For example, something that if price happens to go your way turns into a winner, and if not it's not big deal (eg. cutting your losses short) with positive expectancy? I was thinking about something like going long after every green bar. This would fit "adding to winners" that everyone seems to think is such an important rule (although it does not work for me in my own trading system), and if you happened to catch a big trend you'd make a ton of money. But of course your average cost may be so close to price that a small move against you will turn your winner into a loss. If you get it wrong, whatever, you get stopped out for a few points with one contract. If you get right, tons of contracts in the correct direction (unless price reverses at bad point relative to your average price in which case your winner turns into a loser). This still seems like it requires being able to predict if price is going to trend or not, and if you were able to do that it would make more sense to just short with a big position from the beginning. But maybe this will lead to something useful.
