How accuracy is calculated

Accuracy measures how well you read price — not how much money you made, and not how often you won. A trade that misses can still score well if the price came close, and winning on an easy target counts for less than winning on a hard one. It answers one question: when you picked a target, how near did the price actually get?

Every trade starts at the current price and names a target. The gap between them is how far the price has to travel. Accuracy compares how far it actually travelled toward your target against how far it needed to. Reach the target and you score full marks. Get halfway and you score about half. Go nowhere, or the wrong way, and you score zero.

An example. The price is 63,450 and you pick a target of 63,500, so it needs to travel 50. If it reaches 63,500, that read scores 100%. If it climbs to 63,475, it covered 25 of the 50 it needed, so it scores 50%. If it never rises above 63,450, it scores 0%. The same maths applies whether your target is above or below the current price.

Harder targets count for more. Every target has a price that reflects how likely it is to be reached — a long shot is cheap, a near-certainty is expensive. Reading a cheap, unlikely target correctly says more about your judgment than calling an obvious one, so it carries more weight. A target costing 20¢ weighs four times one costing 80¢.

Closing early is scored the same way on that trade's own row, using how near the price came while you held the position. If we could not observe that — for a close made before we began recording it — the row shows no score rather than a zero. It is never marked a miss just because we lack the data.

Your overall accuracy covers trades that ran to their conclusion — the ones that reached their target or ran out of time. It is the weighted average of those reads: each score multiplied by its weight, divided by the total weight. Trades you closed early show their own score in your history but do not move the overall figure, because deciding when to take your money is a different skill from reading the price.
