Every decision costs something

Every decision costs something

Scalping is a decision machine. Enter or skip, hold or exit, move the stop or leave it, take profit or wait. A busy session might involve hundreds of micro choices.

Decision quality is not constant. Studies of people in other fields, such as judges and doctors, show a steady decline in the quality of decisions as the number rises, with a tendency to default to the easiest option. In trading, the easiest option is often the impulsive one.

That suggests an unglamorous strategy: reduce the number of decisions. Predefine the setups. Automate the exits. Use fixed position sizes. Prepare the plan before the session so that live moments require only a yes or no.

The fewer judgement calls required at speed, the less the quality can decay.

Another trick is making the important decisions early, when the mind is fresh, and routine ones later. Choosing which pairs to trade, which times to avoid, and which levels matter belongs before the opening bell, not during it.

A related idea is the pre-session ritual: choose pairs, mark levels, write the three setups to look for. Everything decided in advance is a decision that does not need to be made while tired.

Some traders also keep a rule that after a fixed number of trades, the session is done. It limits damage on bad days and keeps attention fresh on good ones, and the count is a more reliable guide than feel.

Even small environmental choices count. Setting alerts so they only fire for the pairs and levels that matter removes dozens of micro-decisions about whether a notification deserves a response.

How many real decisions does a typical session demand, and which could be turned into rules?
