BTC moved without our limit — cancelling was the tradeBTCUSDT Perpetual Swap ContractOKX:BTCUSDT.PquantlinesystemsONE CHART — ONE LESSON A limit order is not a promise. BTC squeezed toward the top of its 4H range while our old paper bid at 78,400 stayed unfilled. Once price accepted above 80,035, that bid sat about 2% below the market. It was no longer a controlled retest — it had become a crash-catch. So we cancelled it. We did not chase under 81,266. The plan was rebuilt around the 79,000–79,650 shelf: • Old paper bid: CANCEL • New shelf: WAIT — UNFILLED • Market entry: PASS • Structural invalidation: 77,554 The lesson: patience means waiting for valid location, not staying loyal to stale coordinates. Paper research only. No live fill. No retroactive entry. Follow for the outcome update.
