Well usually when you are in a trade you think that the return is superior to not being in it. Finding times when this is true looking backwards becomes more difficult when the number of random events increases as time passes. The evidence is the signals are extremely weak and decay very fast and you have to go so far into the tail that they occur at extremely low frequency. So to make money you have to have a great number of signals and low holding times
Well yes, the lower the time frame you go the more money you can make, but at some point you get diminishing returns. however, that is not directly correlated to the pattern being different. It becomes more difficult due to catching shorter moves increases the pain of commissions, potential slippage, missing trades due to the speed of the movement and increased likely hood of mistakes.
Completely can appreciate and am aware of that. But just because that is the case, doesn't mean the patterns are any different or have changed, it's just more of a human capacity issue / common sense issues regarding commissions, slippage and mistakes.
For day trading I find more mid-range time frames to be the best, for me personally. Still allows you to capture a large portion of the move, but is also quick enough to trade both sides of the market, if you don't have any high probabilities of it being a super bullish or super bearish day.
Honestly, in the end am only concerned about if what I am doing works and making money. I don't want to be wrong on purpose, but even if my theories are incorrect and I am misleading myself about what I am actually doing, in the end it is working in backtesting and live trading. That is my focus is making money and improving.
