How important is the win percentage?

  1. This conversation reminds me of the crazy story regarding trading guru Robert Hoffman that sent the electrons flying in the trading world several years ago.

    Main thing I pay attention to is account balance and daily P&L.

    Also:
    R:R of pattern entry signal related to trading range and volatility

    Profit consistency potential relative to similar patterns recently traded

    Relative strength vs alternatives


    Re ranges eg see 90d range during selloff, I bought MGM near $7 because of wide range chart, similarly I think there's big upside in inverses like SDOW SRTY SPXS etc, am now waiting for 2day highs to scale in

    I'm kicking myself for not buying more MGM under 10, bought a little yesterday into the close, will scale, it's a slow mover, may recover to 30s over long timeframe 4-6 months, will sell if loses 12, good luck!

  5. Yes, I understand

    I did not want to buy all at once either. So I just been buying in partials as it dips. But I am done investing in MGM. Now just time to hold it.

    there's a tastytrade youtube video interviews that one 'Rising Star' claims 80% win rate 24% P&L

    is it about win rate or overall P&L or a combination, with what minimums for each are considered great?

    Counter-point: percentage matters less than expected value.

    This is sort of the idea behind poker and other table games. Your edge might be 1%. But if the expected value of the game under advantaged play is positive you will make money so long as you have a bankroll to take in the volatility.

    Win percentage is a nice metric to tell the props though, and to be fair expected value in a trade can be hard to nail down in concrete numbers. But again, if you win 98% of the time, but 2% of the time you lose more than you gain, you're in a negative expected value play.

    most important is the ' average loss'. or the one bad trade. can blow your account.
    never average down. cut losses.
    and not able to stop trading when trader is somehow in a losing streak for some reason. they've loss control.

    Counter point : Expected Value matters less than Betting Size.

    You said it though:
    You will make money so long as you have a bankroll to take in the volatility.

    Do Not Over Bet.
