1. Don't be Greedy.
2. Understand how far an average swing, day, 3 days or long term move is on average.
3. When arriving at extreme of "2", stop taking trend trades. Most of my losses occurred at these extremes.
4. For day trading, make reasonable goals, then cut back size 80%.
5. Study winning trades, very little gained from losing trades in my case.
6. Can mix in TA with Price action, just don't go nuts, breaking of highs/lows by small increments shows slowing down and reversals often.
7. Breakeven trade requires one tick profit.
8. Read books about charting, do more backtesting.
9. Have well defined Trading Plan with every conceivable answer to what might happen once in a trade. Each day for long while, more is added.
10. Each market has it's own personality, have to study each to be able to trade.
11. Don't be Greedy.
