Paper Trading

Live simulation — every strategy starts with virtual $1,000 and trades against real Kalshi markets. No real money. Updated every scan.

Bitcoin 15-minute paper experiment

Compare opposite Bitcoin outcomes on Kalshi and Polymarket after fees.

Paper only

The exchanges use different price sources. Both legs can lose. This is a research experiment with simulated fills, not guaranteed arbitrage.

Separate virtual cash for each venue. Kalshi fees reduce cash; Polymarket buy fees reduce shares received. Instant fills on both venues are assumed. Actual settlement outcomes are recorded independently. These results are separate from live earnings and the other paper strategies.
