Trading in the Dumb Zone.

Last night was a prime example. Flagging up and down 100$ averaging 8950. Thats the dumb zone, dont trade there, if anything on each top of flag move a little into into USD awaiting confirmation of up or down, whether or not its a bull flag, bear flag, wedge or pennant you are playing. Wait for confirmation of a move up or down. Losing a little BTC value if it goes up is worth it, every single time, because what if it doesn't?
Sure if it does you may lose 1% of what you sold off re entering, but if it fails, you lost a major opportunity to increase your position.

Price Averaging and Staggering in and out:
This is a HUGE one, esp when in the dumb zone. Yesterday when BTC was flagging that 8950 range, I set buys at 8820, 87XX, 86XX, 85XX, 84XX and 83XX, with the largest buy at 84(where i prefered my average to be and what i saw as the bottom of a dump down) While I had Sells of my current Stack between 9150(smallest sell) 92XX 93XX up to 96XX, with largest being between 94 and 95.
While those were the standard at that point, note we do adjust as market conditions change. sometimes making a larger buy/sell in a different area as we see it, but still making those scaled entries and exits to mitigate risk and exposure to a break down, as well as a possible breakout in case we aren't watching. While sure if we sell our entire portfolio and it drops 10% thats an awesome position increase, but the risk to reward is exponentially higher than when we take a modest average of 3% gain overall without exposing ourselves to a massive change.

Stop worrying if you are wrong and some buys / sells do not hit. Or you did not exit in time, or anything crazy like that. There is always another day, and if you aren't completely exposed, your loss is not that great. You can always make it back tomorrow or a week from now, or a month. It does not matter. Focus on the next trade and ignore the losses. Put limit buys/sells and go to sleep when things get messy, trading in panic or negative mood - is losses guaranteed.
Most of the best hedge fund managers lose 80% of their trades, but they are mitigating risk properly so they are not losing a lot of money just more trades, while the 20% they win make the entire year of their profits.
