The needle in the haystack

In A pair of Aces we saw Robert protect his capital when the odds are stacked against him, and "make hay" when he knows he has a trading advantage. We now explore why we sometimes consistently lose money.

Taking Robert's first trades of the day as an example, we'll see what his trading metrics reveal:

In this case, every metric is reduced on his First Trade of the Day.

Win Rate

This trader typically hits a lot of winners (65%), with his winners being smaller than his losers (each winner is 0.61 times each loser on average).

Robert's Win Rate drops from a very healthy 65% to 45% for his first trades of the day.

Risk: Reward

Secondly, his Risk: Reward ratio - which is already quite low at 0.61 - drops to 0.27. This makes his winners only about one quarter the size of losing trades.


And thirdly, his Disposition ratio is showing that while Robert is still spending more time in his winners than losers (1.1 times), it is lower than his usual behaviour of spending 1.7 times as long in winners.

So what's happening?

There are 2 reasons why performance can degrade:

  1. Market conditions - it may be that if all first trades are entered during (for example) the US market open, the higher volatility doesn't suit this trader.
  2. Robert's emotional state - these trades represent Robert's re-entry into trading after a break, which may have an impact.

Robert examined his trades in detail, he realised that his undisciplined performance was down to his personal emotional state. When Robert gets to his trading station, he can't wait to get back into the markets. This was causing him to be less disciplined about his trade setups.  On his first trades of the day, he was even more keen than normal to get a head-start on his trading day.

What did he do?

Robert gave himself a new rule. He has to wait at least 15 minutes before he puts on his first trade of the day. While this causes him to miss some good signals, overall it is curbing his over-enthusiasm to trade irrationally and his metrics have started to improve.

He has committed to use very small size until he sees a marked improvement in his metrics.
