Just doing the same trades every day allows me to perfect them. Trading the same market helps too, so you know the fingerprint of the market well and can adapt to its changes over time as they occur.
After a trader has become CP, he/she can trade more than one market at a time but certainly not before. Focus, repetition, one chart and one market is my recipe. Repeatedly taking these high probability trades creates mastery over time.
I loved the push down in the ES yesterday in the last hour. It gave us a neutral day with price hitting support of the POC. A great buy which I leaped on and was rewarded. These are not easy trades to make unless you have done all the backtesting to show how high probability they are.
