Common mistakes: trading without a question.
A chart can catch your eye without there being a clear reason to act. Before looking at a signal, state what you want to evaluate: a price hypothesis, an exposure or a cost. Without that question, it is easy to keep adding indicators until you find one that confirms what you already wanted to do.
Mistaking activity for progress
More trades do not mean better decisions. Each entry and exit can add commissions, spread and exposure. A review should include what you decided not to do, because avoiding an incomprehensible trade can also be part of a consistent process.
Measure the total cost and the time you spend supervising. If a tool produces more alerts than you can interpret, narrow its scope before adding instruments.
Copying a strategy without understanding it
A configuration that seems to work in a demonstration may depend on different conditions. Ask for the data, the period, the limits and the behaviour when errors occur. Do not use a favourable track record as a substitute for that explanation.
Write in your own words when the strategy stops making sense. If you cannot do that, you need more information before enabling orders.
A minimal record
Note the date, the reason, the parameters, the expected cost and the review condition. Afterwards compare with the result without erasing mistakes. That record helps to distinguish a poor hypothesis from an execution that differed from the plan.
- One question before a signal.
- One limit before a position.
- One review after the result.
