How often price has actually come to a strike that many implied moves from where it started, beside what the option’s own price implied at the time, over the contracts this board's own expiry belongs with (8-21 days to expiry). That implied figure is for ONE side, so it is what each of the two side columns is read against; the last count is for either side and has no figure beside it, because the chance of reaching one of two is not twice the chance of reaching one. Over this history, a strike that far above was reached about 41 times in 100, over 2,167 past cases; its own price implied about 43.

How much of the premium was still there, measured from 30 sessions before expiry on the same contract — never across a roll, where the change of contract would show up as decay. At at the money and 7 sessions left, about 67% of the premium was still there, over 508 past cases; a quarter of the time it was worth more than when it was written.

Price and open interest read together, on the nearest contract that has not expired. A session where the contract changed carries no change, because the two contracts are different instruments at different prices.
What the board is, and is not
Open interest and its change are the exchange's end-of-session numbers. The action beside each strike names what the price and the open interest did together — long build-up, short build-up, long unwinding, short covering — and is a description of the session, not a forecast. The heaviest call and put strikes are shown even when they sit outside the displayed band, marked as such, because clipping them to keep the row count tidy would hide the two numbers the board exists for.
The 1-minute live version of this same board is on its way. It will run the identical code over the live stream, which is why this one computes nothing a replay could not reproduce.
