The Importance of Closed-Candle State Finality in Market Screening

## Why Interim Price Ticks Create Noise In volatile cryptocurrency spot markets such as Binance and MEXC, intra-candle spikes frequently breach key levels only to retrace seconds before the bar closes. Entering trades during an unclosed candle introduces significant execution risk because the candle's open, high, low, and close (OHLC) values have not settled. ScalpLens enforces a strict **closed-candle rule**: 1. **State Persistence**: A setup condition is only evaluated once the bar timestamp has officially lapsed and finalized. 2. **Immutable Snapshots**: When a market condition is confirmed on a closed bar, an immutable snapshot of that exact moment is generated with a server-enforced 20-minute lifetime. 3. **No Retroactive Rewrites**: The desk never paints a signal and retroactively removes it. Once confirmed, a record is permanently fixed in the ledger. ### Eliminating the 'Chasing Wick' Fallacy Traders who enter on forming wicks often find themselves buying local tops or selling local bottoms. By requiring the close of the bar: - Indicator and baseline values become final and deterministic. - Mathematical models evaluate completed price distributions rather than rapid tick oscillations. - Execution slippage and impulsive emotional entries are systematically minimized.
