This will not be the most popular post I'll ever write about trading psychology, but I believe it's my best and certainly my most heartfelt.
Gut feel without understanding leads to the trading of randomness.
Backtesting without understanding leads to the trading of randomness.
Nothing substitutes for a reasoned understanding of how markets behave and a disciplined execution of trades that reflect that understanding.
I hope this post points the way to your shining success as a trader or at least convinces you to pursue your shining success elsewhere.
