How the NOXY screener works
Crypto order book screener
Find visible buy and sell walls near the current price on Binance and MEXC Spot. Compare markets in one live table, then open the pair on its exchange. Free access, no account or API keys.
What is an order book wall?
A wall is the aggregate displayed quantity at one price level. It may contain many orders from different participants. NOXY observes this liquidity; it cannot identify who placed it or establish that it will remain available.
Compare distance and persistence
Inspect the wall’s quote notional, distance from the current price and observation score. The score combines relative size, reachability, persistence and concentration. Open its breakdown to inspect the published contributions; the score is not a probability of a profitable trade.
Check coverage before comparing markets
The table covers USDT spot pairs on Binance and a ranked subset on MEXC. It does not observe every price level or every MEXC pair. Coverage and age are published above the table. Missing evidence stays unavailable; the screener submits no orders.
Crypto volume scanner
See which spot markets traded unusually high volume in the latest closed 5m, 15m or 1h window. Read the multiple, USDT turnover and price change together, without opening each chart first.
A matching interval baseline
Relative volume divides the latest interval’s quote volume by the median of non-overlapping intervals of the same length in the preceding 24 hours. The current interval is excluded. A reading of ×3 means three times that median, not a forecast of the next candle.
Liquidity and timing matter
The initial shortlist requires at least ×2 relative volume, 10,000 USDT in the interval and 100,000 USDT in 24h. These are adjustable exploration filters. All readings use closed five-minute bars; choose 15m or 1h for a longer window. This is not a tick-by-tick early warning.
Missing history is not zero volume
Each interval needs its own contiguous 24h baseline plus the latest window. Gaps or a zero baseline withhold the ratio. Stale windows leave the unusual-volume shortlist. Volumes are in USDT, not converted USD, and a surge does not establish its cause or predict a pump.
Crypto volatility screener
Compare active spot markets by measured 24h volatility. Keep liquidity in view and inspect price movement, trading volume and nearby order book walls before opening the exchange.
Volatility is not price direction
NOXY measures realized volatility as the square root of the sum of squared logarithmic returns between consecutive five-minute closes, expressed as a percentage. A market can travel widely and finish close to its starting price. Read signed price change separately.
Start with liquid markets
The preset initially filters for at least 100,000 USDT of 24h turnover and ranks available volatility measurements. Adjust the volume threshold and exchange filter. A high reading identifies a market for manual inspection, not a recommendation to buy or sell.
A complete day of returns
The calculation requires 289 consecutive five-minute closes to form 288 returns. Rows without sufficient contiguous history are excluded from this shortlist. Only active rows participate; inspect the snapshot freshness and coverage above the table.
