Most avoidable mistakes involve confusing two things that look similar: a headline and a rule, a quote and a fill, or a reward and a profit. Use this ten-point review as a practical checklist before you trust an account operation, a forecast or a performance claim.
Mistakes 1–3: misreading the contract
First, do not rely on the market title without checking the rules. Second, do not substitute a news report for the named resolution source. Third, do not confuse the event deadline with final settlement. For each market, write the precise outcome, the evidence that establishes it and the relevant time. If those cannot be stated clearly, you have a contract-reading task before you have a forecasting task.
Mistakes 4–6: misreading execution
Fourth, do not treat a displayed midpoint as a guaranteed execution. Fifth, do not count an open order as a filled position. Sixth, do not omit the costs of a planned exit. Inspect quantity, price, order status and charges together. Recalculate a hypothetical result using actual fills rather than the most favorable price visible when you first considered the idea.
Mistakes 7–8: misreading account operations
Seventh, do not assume that every address associated with your account serves as a funding destination. Follow the selected route in the official interface. Eighth, do not let a third-party guide become a place to submit credentials or login codes. Educational content can help explain a process, but it should not need access to your account to display an article.
Mistakes 9–10: misreading performance
Ninth, do not count several correlated positions as independent successes. Tenth, do not rewrite your forecast after the result is known. Keep a dated journal of the evidence, probability estimate and execution assumptions. Review losing as well as winning decisions. Record rewards separately from trading gains and losses so one attractive number does not conceal the overall economic result.
Questions & answers
Which mistake should I address first?
Begin with the contract definition. A trade cannot express the intended forecast if it answers a different question.
What makes a useful trade journal?
It records the information and assumptions available at the decision time, including unsuccessful ideas and actual execution costs.
