BTCUSDT 15m - Retest of 82900-83307 supply OB after BOS down imp Bitcoin/USDT OKX:BTCUSDT TheChartist_Code2trade Market structure and supply/demand zone analysis combining BOS impulse identification, order block retest, and range/equilibrium mapping. Context: price staged a sharp impulsive decline from 83530 to 80400 before consolidating into a tight equilibrium range between 82380 and 82870 over the past several hours. Key levels: the 82900-83307 zone marks the prior supply order block and swing high that preceded the breakdown, now being retested from below; 81500-81900 marks the liquidity support zone inside the earlier range. Scenario: bias favors short on a retest of the 82900-83307 supply zone, with price currently pressing into its lower edge near 82950; target is the 81700 support/liquidity zone. Invalidation: a clean close and acceptance above 83330 would invalidate the short bias and shift structure back toward bullish continuation. Educational chart analysis only, not financial advice.
