Place a resting order that fills only when the market reaches your price, and fills AT that price. type "limit" = a pullback entry (long below the market, short above); type "stop" = a breakout entry (long above the market, short below).

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.
| Name | Required | Description | Default |
|---|---|---|---|
| slippage | No | Fill against yourself the way a real order book does: 0.01% crypto majors, 0.05% other crypto, 0.005% forex, 0.02% stocks/metals/indices. | |
| margin_tiers | No | Raise maintenance margin with position size, as an exchange risk-limit table does, so a large position is liquidated sooner. | |
| margin_venue | No | binance | bybit | okx | bitget | mexc | kucoin | gate | kraken | hyperliquid | coinbase, or "marginpad" to reset. Omit every field to read. |
Backtest with the real routes: replay one past UTC day on MarginPad’s 1-minute candles. With symbol+day it STARTS a replay (speed = market seconds per real second, 1-600, default 60): from then on paper_open / paper_positions / paper_close act on a separate replay journal priced at the candle under the cursor, with stops, targets and liquidations checked on every candle. With no arguments it reads the status (cursor, price, progress, candles up to the cursor). With act "stop" it closes everything at the cursor and returns the summary. Requires an API key.
