'Buy low, sell high' or 'Buy high, sell higher' always seem to me not to have any real meaning or alternatively are just circular expressions. Do you 'Buy low, sell high' or 'Buy high, sell higher'? If the next day's play is at higher prices levels (say, Dow) well, sure I can only buy higher and will have to sell even higher to score a profit. Presumably, like certainly some others I do not have a price level perception as an important parameter; that means when each days play comes up I don't really care whether the market, say the Dow, is at 9600 or 9900 or some other general level. I'm not playing trends per se and also I day trade without the need for carrying positions intra-day; the purpose of my play is to exploit each days major gyrations. To explain my positioning, my strategy is an own system whereby the most recent past movements are the important parameters; thereby I have the pre-determinates for each new days play. Obviously months and months of research go behind this. Incidentally this is not aimed against those who rely on price levels and trends. Comparing notes is always interesting .. thats my general aim, if I may say that. If 'Buy low, sell high' or 'Buy high, sell higher' is useful at all how do you follow either prescription?
