Pitch and thresholds
Pitch can follow price, execution volume, prints per second or fixed bid/ask tones. Set base frequencies, variation and ear separation. Trade sounds provides minimum size, large-trade threshold, sound interval and alert cooldown.
Volume calculation and ladder alerts
Available modes include individual trades, rolling time, volume at price, adaptive intensity, nearby price volume, captured profile and relative profile. Profile modes accumulate from monitoring start. Use the Squawk ladder to configure price alerts for its selected workspace.
