I went through the following cycle several times: inconsistent results from intraday trades lprompted me to a) avoid pushing trades in that time frame (increase selectivity) and b) reducing trade size. Profitability then becomes more consistent; confidence returns to the method/time frame, so an increase in motivation and position size follows. Greater expected profitability leads to higher proclivity in looking for and initiating trades; selectivity falls and profitability soon deteriorates. Frustration and loss of confidence signal a return to inconsistency. Cycle repeats.
As optimal selectivity and position size are inversely correlated in this cycle, its repetition = continued losses. Breaking this chain entailed taking a step back and recognizing the irrational ebb and flow of expectation and results; as is often the case, progress came from consciously reversing natural instincts, but it didn't come easy for me. Anyways, just an example of how things aren't so clear cut when it comes to simply increasing position size.
