BTC/USDT Fair Value Gap detector

Bitcoin is the pair everything else quotes against. A 4h Fair Value Gap on BTC/USDT perpetual is not just another green box — it is often the reason ETH and SOL print their own 15m gaps an hour later. This page is the live Binance USDT-M map for that pair, not a generic “BTC is the largest crypto” stub.

Why Bitcoin gaps are different

BTC trades through Asia, London, and New York without an equity-style close. Displacement that leaves a 15m FVG during the New York open is usually a continuation of a London range, not a random three-candle toy. On 4h, those same impulses collapse into one or two zones you can actually keep on a screen.

Alts inherit that. If BTC leaves an unfilled bearish 4h gap overhead, a bullish FVG on a random USDT alt is fighting the index. Scan alts after you know where Bitcoin’s open imbalances sit — the market scanner is the second step, not the first.

Timeframes that matter on BTC

• 1d / 4h — few gaps, wide, slow to fill. Use as bias. A 4h BPR after a sweep-and-reclaim is the cleanest “balanced” read this engine will draw.
• 1h / 15m — execution. Same three-candle rule, more boxes. Hide raw FVG and leave BPR if you only want overlaps.
• 5m — useful around a known 1h zone, noisy as a standalone BTC map. Funding prints and liquidation cascades create gaps that never get revisited.

What you will see

The analyzer pulls Binance USDT-M klines, marks bullish/bearish FVGs with the low > high[2] / high < low[2] test, and paints purple BPR where opposite gaps overlap inside 50 candles. The last candle streams on the futures WebSocket. It does not know funding, open interest, or your stop. Those are still your job.

Not a buy/sell call. A gap on BTC can sit unfilled through an entire trend.
