Which trading mistake is costing me the most money?

How this is calculated

• Each entry adds its dollar cost to that mistake category's running total. The categories are then ranked from most to least expensive.
• Estimate the cost as the extra loss beyond what a well-executed version of the same trade would have cost, for example the extra size on an oversized trade, or the extra loss from a stop that was moved.
• This tracker only exists in your browser tab for this session and resets when you close or reload the page. Log mistakes as they happen for the most accurate picture.
• A single big number in one category is more actionable than a vague sense that you "make mistakes sometimes." Fix the top category first.
