Not Every Losing Example Is the Same Kind of Mistake
Classify practice problems as mechanics, data, planning, execution, or review issues so the next exercise addresses the actual cause.

Key idea: A specific error category points to a useful correction; a vague label such as bad trade usually does not.
When every disappointing example is labeled a bad trade, different problems become mixed together. Selecting the wrong expiration, using a stale quote, and following a reasonable plan through an unfavorable outcome are not the same event.
A simple classification system helps you choose a correction that matches the evidence. The categories are tools for learning, not labels for judging yourself.
Start with mechanics and data
A mechanics problem concerns the instrument or instruction: wrong contract, misunderstood multiplier, incorrect order type, or unverified status. A data problem concerns the information: stale quotes, mismatched timestamps, an incorrect benchmark, or a misunderstood field.
For a hypothetical example, buying a different expiration from the one in your plan is a mechanics issue even if the position later gains. A favorable outcome does not erase the mismatch.
Separate planning from execution
A planning problem means the intended process was incomplete or internally inconsistent. Perhaps the thesis had no invalidation condition or the horizon did not match the contract. An execution problem means the plan was understood but the action differed from it.
Do not call something a failure to follow the plan if the relevant instruction was never written. The correction may be to clarify the plan, not to demand more discipline around an undefined rule.
Identify review errors too
A review can introduce its own mistakes: choosing the best later exit, omitting unsuccessful examples, or explaining the outcome using information unavailable at the time. These errors can make a practice record look more informative than it is.
Preserve the original note and add the later analysis separately. This makes it easier to see where the evidence ended and hindsight began.
Leave room for ordinary uncertainty
Not every unfavorable outcome contains an identifiable process error. If the mechanics, data, and plan were reasonable under the available information, record the outcome without inventing a mistake to explain it.
Choose one primary category and any secondary issue for each example. Then assign a small corrective exercise: contract identification, source verification, plan writing, order-status practice, or a more disciplined review.
Try classifying five examples before changing your strategy. Tradex's structured learning and simulated review can help turn those classifications into targeted practice, so each new session addresses a real gap rather than a general feeling that something went wrong.
