Quote from kut2k2:
This is the main problem with discretionary trading: too many opportunities to second-guess yourself. Mechanical trading has predetermined exit(s) and IF you have a properly backtested and profitable system, it's just insane not to follow all the entry and exit signals.
Exactly!
Having been guilty of letting losers run and cutting winners short and having later worked with some traders who did the same thing, I understand the mindset that causes it.
There are the three situations I've observed (and also been guilty of):
- The trade immediately runs against you and you hold and hope it will at least get back to even. If it does, you scratch the trade (cutting any chance of a profit) and if it doesn't you take the full loss (or worse if you move stops further away or average down).
- The trade stalls and consolidates around your entry price and you finally scratch the trade because it isn't moving and you get nervous. This also eliminates the chance of a profitable trade.
- The trade runs in your favor and you immediately move your stop to break even to prevent the chance of a loss, or you take a small profit at the first sign of price stalling or pulling back. This results in a break even trade or a small profit.
The psychology behind these behaviors is the desire to relieve the discomfort that comes from the environment of risk and uncertainty. By preventing the chance of a loss or by scalping a tiny profit to get the pleasure of a reward, you feel "safe" from the market "taking away" from you.
It's often said that we attract what we fear. By fearing any loss in the market, we behave in ways that prevent gains.
The net outcome is that the only thing we allow to run is the losers.
