FillSense

FillSense is a web app (with optional mobile companion) that estimates the probability, time-to-fill, and expected slippage for specific options orders before you submit them. You enter ticker, expiry, strike, side, order type, and limit price; the app pulls live options quotes and recent prints, then simulates queue position and microstructure behavior to show a realistic fill forecast. It also flags liquidity traps (wide spreads, stale quotes, low size, sudden IV jumps) and suggests safer alternatives (different strike/expiry, smaller size, staged orders) while keeping your intent intact. This is not a broker replacement: it’s a pre-trade decision layer that reduces “why didn’t I get filled?” frustration and costly chasing. The hard truth: many retail options losses come from execution and spread bleed, not just bad direction—this app targets that directly.
