Start with the clocks
Record the execution timestamp, source update time and the time you actually received the result. Keep the session date and time zone consistent. A refresh animation or a one-minute polling interval does not establish one-minute end-to-end latency.
Pineify’s Market Insights options-flow view uses a 60-second polling interval with conditions and API caching. It is a research interface, not a tick-by-tick execution feed. If source timing is unavailable or a record arrives after a move, do not treat that record as evidence that you could have acted before the move.
Match the print to an executable market
Check the current bid, ask and displayed size for the same contract. A historical execution price or last close is not a current fill offer. A sweep label does not promise that its price remains available, and an aggregate may span more than one execution.
For illustration, buying a standard 100-share option at a $2.50 ask and immediately selling at a $2.30 bid loses $20 per contract before fees, assuming both quotes are executable and unchanged. A midpoint simulation at $2.40 would hide that spread cost. Include costs and slippage assumptions in any evaluation.
Separate same-day expiry from other contracts
A 0DTE option expires on the trading day being considered. Do not mix its behavior with longer-dated contracts merely because the ticker and strike match. Time decay, gamma and changing implied volatility can alter option prices even when the stock moves in the expected direction.
Read the contract’s exercise style, settlement method, final trading time and your broker’s handling rules. Index, equity and ETF options are not interchangeable. A closing plan depends on the actual contract and execution conditions; a flow label does not control assignment or settlement risk.
Keep a record that excludes hindsight
Before looking at the later outcome, record the data received, the rule being evaluated, the intended holding window and the conditions that would invalidate the observation. Log missing or stale records as well as interesting ones. Evaluate the same rule across the full selected sample.
There is no universal best hour, premium threshold or put-call ratio that makes flow profitable. Compare like-for-like session windows and use data you actually possess. Pineify’s public flow guides do not publish an external options-flow series into TradingView; Pine Script generation cannot reconstruct an unavailable historical feed.
