We may start by setting concrete goals and steps toward reaching those (no more than three), and working on those intensively produces the best outcomes over time.
Here are some ideas that may help:
Generating better ideas: Looking back in time, most traders can find plenty of missed opportunities. Many times the opportunities are missed simply because we were not focusing on the right markets or the right stocks in the right time frames. Improving our data set, looking at more things in different ways, is an important step in feeding our pattern recognition. Reading fresh perspectives from knowledgeable writers and speaking with insightful traders similarly can fuel our creative thinking. I suggest choosing a good site as a source of readings and podcasts to keeping a daily Evernote journal of market-relevant ideas. Indexing those ideas over time should produce a valuable database for future reference.
Better risk management and opportunity management: It helps to look at the tails of your P/L distribution. Please Size positions appropriately, utilize reasonable stops, ensure that multiple positions are sufficiently uncorrelated, etc. Cutting opportunity short can significantly weigh upon overall returns. Plotting your P/L for each trade and looking at the shape of the distribution will tell you a great deal about your management of risk and opportunity.
Better entry and exit execution: It doesn’t show up in the P/L stats directly, but looking at how your trades performed after you entered and after you exited will give you some idea as to whether your execution is adding value. Too often traders will chase market moves and enter at bad levels and/or puke out of trades on noise and exit prematurely. A review of market paths following recent entries and exits can identify those problems. No one should hold themselves to buying the low tick and selling the high one. Overall, however, you should be aware of the heat you take on trades once you enter and the amount you leave on the table when you exit.
