You know, sometimes I postulate heed things together with milk shiver my head. Then I postulate heed them over again together with curlicue my eyes. Finally, I maintain hearing them together with brand a valiant endeavour to non throw upward inwards my mouth. I mean, really, you lot don’t desire to hold upward rude to people, exactly there’s alone thus much 1 tin flame suffer when platitudes pose every bit wisdom.
Take the virtuous advice that trading success hinges on “following your process.” Please. WTF does that mean? Here’s a procedure for you: I drinkable Turkish java every morn together with and thus examine the java grounds at the bottom of the cup. If the grounds by together with large settle at the top of the cup, it volition hold upward a bullish twenty-four lx minutes catamenia inwards stocks together with I purchase at the opened upward together with sell the close. If the grounds settle at the bottom of the cup, it volition hold upward a bearish twenty-four lx minutes catamenia inwards the marketplace together with I sell the opened upward together with encompass at the close. If the grounds settle at the left side of the cup, it volition hold upward a tranquillity twenty-four lx minutes catamenia together with I’ll sell volatility. If the grounds settle on the correct side of the cup, volatility volition expand together with I volition hold upward a vol buyer. And if the grounds are evenly settled at the bottom of the cup, there’s no border for the twenty-four lx minutes catamenia together with I’ll drinkable a 2nd cup.
Now that *is* a process. But does my trading success hinge on fidelity to my process? Of course of report not! That’s because, inwards the linguistic communication of psychometrics, the procedure is reliable exactly non valid. It is repeatable exactly random. Being procedure driven is necessary, exactly non sufficient. Before 1 waxes poetic most next a process, it helps to define a procedure worth following.
Or let’s accept the cliche that 1 shouldn’t assay to predict markets exactly instead should heed to markets together with follow their lead. I don’t know what that means. Does it hateful that you lot are supposed to naively extrapolate the final X bars on a nautical chart together with blindly assume that they volition conk on their pattern? Does it hateful that you lot impose expectations of momentum together with tendency on every marketplace regime? Does it hateful that you lot utterly lack backtesting skills together with are bravely turning that into a horse-whispering virtue? Whatever.
So here’s a keen experiment that anyone tin flame conduct. Define a trading organization that takes the final X bars together with extrapolates from them to the adjacent X bars, buying the X+1 bar opened upward when the extrapolation is positively skewed; selling the X+1 bar opened upward when the extrapolation is negatively skewed; together with standing aside when the extrapolation displays no directional bias. That way you’ll ever own got a replicable procedure *and* you’ll hold upward next what the marketplace is telling you.
Just every bit a lark, I tried the experiment amongst historical data, buying SPX when the per centum of stocks to a higher identify their five-day moving average was to a higher identify 50% together with selling SPX when the per centum of stocks to a higher identify their five-day moving average was below 50%. The information were for SPX stocks specifically, going dorsum to 2006, together with the belongings catamenia was for the adjacent 5 trading days. Buying forcefulness gave an average five-day furnish of -.07%–a modest loss. Selling weakness gave an average five-day furnish of -.44%, a considerable loss. The average five-day furnish over this catamenia was a make of +.15%. In other words, having a robust procedure together with next the market’s atomic number 82 has ensured losses inwards both rise together with falling marketplace environments.
Interesting: the rails tape of the received wisdom is thus pitiful that it’s promising.
