Trading the Spot-to-TWAP Lag in Polymarket Crypto Markets

Day 2 of the Polymarket Trading Bot Strategy Series

In short-duration crypto markets, the external BTC market can move before the rolling TWAP fully adjusts. This creates a temporary spot-to-TWAP gap that can become a useful trading signal.

The basic relationship is:

Spot > TWAP > Strike

If spot is significantly above TWAP, momentum remains positive, and the TWAP is also rising, the bot can identify a potential UP setup.

Measuring the Gap

A simple normalized measurement is:

spot_twap_gap = (spot_price - twap_price) / twap_price

For example:

Spot = $117,400
TWAP = $117,080

Gap ≈ +0.273%

But the gap alone is not enough. A temporary BTC spike can quickly reverse before the TWAP has time to follow.

A stronger signal combines:

Spot/TWAP gap
+
Spot momentum
+
TWAP slope
+
Distance from strike
+
Time remaining

For example:

if (
    spot_twap_gap > GAP_THRESHOLD
    and momentum_30s > MOMENTUM_THRESHOLD
    and twap_slope > 0
):
    signal = "UP"

The bearish setup is the inverse.

Persistence Matters

The key question isn't:

Is spot above TWAP?

It's:

Has spot remained above TWAP long enough, while momentum remains positive, for TWAP to follow?

This helps filter temporary price spikes and weak signals.

A production Polymarket Trading Bot should also account for execution latency, liquidity, spread, slippage, fees, and time remaining. The expected edge must be large enough to justify the total trading cost.

The Key Insight

The strategy is really about information lag:

External BTC Market
        ↓
    Spot Price
        ↓
       GAP
        ↓
    Rolling TWAP
        ↓
    Polymarket

The objective isn't simply to predict whether BTC goes up or down. It's to determine whether the external price move contains information that has not yet been fully reflected in the TWAP.

Before deploying capital, backtest the relationship between the gap, momentum, TWAP movement, time remaining, and actual outcomes.

The edge isn't the gap itself. The edge is identifying when the gap is likely to persist long enough for TWAP to follow.
