feature-f12-open-limitup-block

To block re-entry on an open-limit-up stock after selling, enable the f12_enabled configuration flag. The engine evaluates open_limit_up and sold_today states during the _tick() flow to prevent placing another buy order for that same day.

Open-limit-up entry blocking specifically prevents buying a stock that triggered open_limit_up after a completed sell_today action. Ordinary limit-up re-entry scenarios are handled separately by the entry_blocked state, not by this F12 rule.

To disable the open-limit-up sell tracking protection, set the f12_enabled configuration value to False. This turns off the F12 rule, allowing the engine entry logic to place orders even if sold_today and open_limit_up conditions are true.

Use open-limit-up entry blocking when your trading strategy requires strict risk control against buying a stock back on the same day. It applies during engine entry decisions to stop orders if a stock opens at limit-up and was already sold.

No, the F12 entry block relies on open_limit_up data from universe scanning and sold_today from completed sell actions. Without these inputs evaluated during the _tick() flow, the rule cannot trigger to prevent the order placement.

Your trading system keeps re-entering because the f12_enabled flag is likely False or missing. Ensure your configuration sets f12_enabled to True so the engine checks open_limit_up and sold_today to block the order.
