How does the PSX trading scanner avoid bad data?

Every candidate passes a data-integrity gate before it can produce a signal: feed freshness, OHLC coherence, non-zero traded value, minimum session history, frozen-price detection, unadjusted-spike detection and live-versus-history agreement. Each symbol gets a 0–100 data-quality score and anything below 62 is rejected and listed publicly rather than silently traded.

What setups does the scanner look for?

Range and Donchian-55 breakouts, trend pullbacks to the 20-session average, golden and death crosses, oversold reversion, overbought fades, MACD momentum turns, volatility squeezes, 52-week-high momentum and range breakdowns.

Where do the entry, stop and target come from?

They are volatility-scaled, not round numbers: the stop sits 1.6 ATR-equivalents away or under the 40-session floor, whichever is safer, and the target is 2.6 ATR or the 40-session ceiling. The reward/risk ratio and expectancy are then published alongside the modelled win probability.
