If EUR\/GBP quoted = 0.85200 (23 pips below implied):
\nStep 1: Sell EUR → buy USD at 1.08500   (1,000 EUR → 1,085 USD)
\nStep 2: Buy GBP with USD at 1.27000       (1,085 USD → 854.33 GBP)
\nStep 3: Sell GBP → buy EUR at 0.85200   (854.33 GBP → 1,002.74 EUR)

Signal fires IF AND ONLY IF all four conditions are true simultaneously:<\/p>\n

(1) MaxFeedTimestampDelta < SynchronisationThreshold
\n — All three feeds have updated within ~60ms of each other
\n — No single feed is running ahead of the others<\/p>\n

(2) Discrepancy.Duration >= PersistenceWindow (e.g. 80ms)
\n — Genuine LP discrepancies persist; latency artifacts collapse in 30–100ms
\n — Applied before the more expensive checks below<\/p>\n

(3) abs(FastFeed.RateOfChange, 100ms) < DirectionalEventThreshold
\n — No significant price movement in the preceding 100ms window
\n — A directional event is the most common cause of feed latency artifacts<\/p>\n

(4) CurrentDiscrepancy > LiveMinThreshold × (1 + SafetyMargin)
\n — Computed dynamically from live spreads + commissions + slippage
\n — Safety margin (typically 20–30%) covers execution slippage variability<\/p>\n

Failure of ANY condition → signal discarded, no order placed.<\/p><\/div>\n
