paper_realism
How honestly your paper fills are simulated. By default a market order fills at the live price with no slippage and maintenance margin is a flat 0.5%, which is easier than a real exchange and increasingly so as a position grows. Pass slippage and/or margin_tiers to turn either on, and margin_venue to build on a named venue’s published maintenance-margin rate (Binance 0.40%, Bybit 0.50%, MEXC 0.10%, Kraken 0.60%, Hyperliquid 1.25%, Coinbase 1.33%). Reading returns your setting, every venue rate and the whole size-tier ladder, so a liquidation price never has to be reverse-engineered. Positions keep the margin they were filled with. Requires an API key.
