Open any chart containing m1 and observe the candles. Would you say that the simple fact that at least half the time you'll ussualy have a succession of candles, plus including their dimensions as a factor, going in a certain direcion would be true if every candle has been decided by the flip of a coin? Would you say that when market goes flat for a while relative to the previous wavy condition is a random occurence about the single candle scale determined like a flip of a coin? Would you say that certain news related motions (not neccesarily during the news themselves also) and other stuff I won't go into detail about today but exist and are often very highly deterministic when they happen are all arbitrary? Somehow I don't think so...

With that said, I believe that calling anything beyond the next move (on a pertinent TF for that move) is likely to be arbitrary in the vast majority of instances and calling just another move so the forecast is indeed more likely isn't always possible either but frequently anough so that using lots of practice and application of suitable principles to spot different types of moves - you can decide on the ideal direction and profit from it longer term.
