Supported Exchanges
All bots use post-only limit orders (maker) by default. Taker execution is reserved for stop-loss orders and delta neutral hedging only.
Why Maker-Only Matters
Most perpetual DEXs charge taker fees (2-5 bps) but offer maker rebates — meaning you get paid to provide liquidity. Since every Sigma Engine bot places post_only orders, you never pay taker fees and you earn rebates on every fill.
The difference compounds fast. A taker bot running $20M in volume would pay $2,500+ in fees. The same volume as a maker earns up to $5,400 in rebates depending on the exchange.
Even a strategy with a slight edge (-0.5bps raw) becomes profitable on exchanges with maker rebates. On a slightly winning strategy (+0.5bps), rebates can nearly double your returns. This is why exchange choice matters and why all Sigma Engine bots are maker-only by default.
