Hi fxtime, in systematic models, should one use volume (number of price changes in observed time frame) and then strategies would be based on an objects classification (events that meet the conditions contained in the set of rules which depend on the value of certain parameters). Object—the event—is another candle. And rules are logical sentences like “if the price is greater than the upper barrier of the band” and the parameter is, for example, the upper barrier, which is a variable value. And when positions are opened the current volume should be greater than the average? And volume would be a parameter, say the last 8 candles, in order to trade the next two? R=8/2 or (I have also tested 5/1 on an H1 chart) is it simply better to stick to ROC, as its easy math?
