Market Call looks simple from the outside — pick higher or lower, see if you were right — but there's real mechanics behind how a vote actually gets locked in and later scored. Understanding that mechanism is useful if you want to actually trust the accuracy percentage the tool reports back to you.
Step 1: Locking
Once you cast a prediction, it locks before that trading session opens — you can't go back and change your call once the market you're predicting has actually started trading. This is a deliberate rule: it forces the prediction to reflect your view before the outcome starts to become visible, which is the entire point of the exercise.
Step 2: Resolving against the actual close
After the relevant session ends, the prediction resolves against the real closing price — roughly in the evening, once that day's official closing data is available. Your choice (higher or lower) is compared against what actually happened, and marked correct or incorrect accordingly, for every vote cast on that prediction.
Step 3: The flat-close exception
If the index closes exactly unchanged — a genuine tie — the prediction is voided rather than scored as wrong for everyone who called either direction. This matters because an exact tie isn't really a failed prediction in the way a clear miss is; voiding it keeps the accuracy percentage meaningful rather than penalising an outcome nobody could have correctly called.
Step 4: XP and accuracy, afterward
- A correct prediction earns XP, counted toward your overall gamification progress alongside quizzes and lessons.
- Your accuracy percentage is simply total correct predictions divided by total resolved predictions — voided ties aren't counted in either number.
- Voting on Market Call also counts as a streak-qualifying action, alongside the Daily 5 and academy lessons, toward your overall activity streak.
None of this changes what you should do with the tool day to day — form a view, lock it in, see what happened. It just means the accuracy number you see is a carefully resolved statistic, not a loosely kept scoreboard.

Can I change my prediction after I submit it?
No -- a vote locks before that session's market opens, specifically so the prediction reflects your view before the outcome starts to become visible.
Does a correct Market Call prediction earn anything beyond accuracy tracking?
Yes -- it earns XP, counted toward your overall gamification progress, and voting counts as a streak-qualifying action alongside the Daily 5 and academy lessons.
How soon after the market closes does a prediction actually resolve?
Resolution happens once that session's official closing data is available, broadly in the evening after the next relevant trading session completes.
Why lock the vote before the session instead of allowing changes until the close?
Because the entire value of the exercise is forming a view before the outcome is visible -- allowing changes right up to the close would let hindsight creep into what's supposed to be a genuine prediction.
Lock before the session opens, resolve against the real close, void on an exact tie, award XP for a correct call -- that's the full mechanism behind a Market Call prediction. Understanding it is what makes the accuracy percentage the tool reports back something you can actually trust, rather than a loosely kept scoreboard.
