Quote from konviction:
Maybe keep a journal (just something simple in notepad) of your thoughts before and after a trade. What did you like about the trade, and what got you in before you took it?.. and it couldnt hurt to take a screen shot of the trade to give yourself that visual aid.
Go back at the end of each week or month and review your trades...you should start to see some common issues arise. I've been writing down my thoughts on my "pitchfork" thread and I keep a screen shot of every trade. It's really helped me in the past, because sometimes I'll take a trade, and later wonder wtf I was thinking.
This is a great idea. Each day I do a bar-by-bar analysis of my trading instrument (crude oil/CL), which provides me a measure of how much I've allowed bias, distraction and failure to follow my rules to affect me that day.
I use a 5-min chart for setups/signals. What I do once the market is closed, is I move the chart off screen except for the hour or two before I start trading. I then reveal one bar at a time and ask myself whether the bar set up as a pure signal bar (enter a trade immediately upon close of the bar) or whether it set up as a conditional signal bar, meaning I enter the trade as soon as price breaks a specific level (such as the signal bar's high, low, open or close).
I make note of the entry price, stop price and profit target price and then reveal one bar at a time until either the stop or the target is hit, logging the P/L on the trade. Then I move onto to the next signal, until I reach the close.
Then I compare this to the trades I actually took that day. This gives me the cost of mistakes (bias, distraction and rule violations).
Today, for example, my first trade was entered 4 ticks late ($40) because I didn't put on the trade immediately upon close of the pure signal bar (distraction) and then I made the mistake of letting my bias override my profit target strategy under these particular conditions and as a result ended up with $50 profit on the trade instead of $200 because price twice dipped 3 ticks below what should've been my target and instead I trailed a stop hoping for more than that. There are times to hope for more, but price in a range around a flat 20 EMA is not one of them. Cost of mistake: $150
I failed to take several other signals for one reason or another (bias, distraction, overthinking). Cost of mistakes: a lot
I then took a conditional signal trade off the news, and instead of targeting a measured move (very common off this type of setup), I took profits when price pivoted after falling really fast. It was an emotional reaction to the fact that a large P/L was showing as well as bias that price had gone "too low". The target I normally use in this type of setup is a measured move plus 4 ticks cushion which would've taken me out 1 tick above the low of the day. Cost of mistake: $430
My short bias kept me out of two very decent long trades. Cost of first mistake: $350 to $550 depending on whether I chose the hard profit target or trailed a stop. Cost of 2nd mistake: $490
Interestingly, my final trade was off a signal I saw on the 1-min chart (the 5-min chart would not have provided a signal because the trade was counter-trend). One of my trading roomies and I discovered we'd both shorted at the same off this setup that was easily seen on the 1-min chart. Since it was counter to the prevailing trend, profit target should've been 20 ticks, standard CT target. But we both got greedy thinking the trend had turned and ended up out break even after price moved through target zone TWICE and finally reversed. Cost of mistake: $200
When my cost of mistakes is over 3x my daily profit, my trading gets a very bad grade!
