Account and leverage#

Balance#

let b = trader.get_balance().await?;
println!("{} total, {} available ({})", b.total_balance, b.available_balance, b.currency);
for asset in &b.balances {
    println!("{}: free {} locked {}", asset.asset, asset.free, asset.locked);
}

AccountBalance fields:

Field	Type	Notes
`total_balance`	`f64`
`available_balance`	`f64`	Free to use.
`currency`	`String`	Usually `USDT`.
`margin_balance`, `used_margin`	`Option<f64>`	Perpetuals.
`unrealized_pnl`, `realized_pnl`	`Option<f64>`
`balances`	`Vec<Balance>`	Per asset: `asset`, `free`, `locked`.

Optional fields are None when the exchange does not report them.

Leverage#

trader.set_leverage(Some("BTCUSDT"), 10).await?;

Spot traders generally treat this as a no-op that returns Ok(true).
Some exchanges return an error when the leverage is already at the requested value. Bybit treats "leverage not changed" as success.
The maximum leverage depends on the symbol and on your account tier. SymbolInfo.max_leverage and the tradersdk-leverage-cache crate (cached per-symbol limits) help you stay within it.
Passing None for the symbol is adapter-specific. On Bybit it returns Ok(true) without changing anything. Pass the symbol explicitly.

Fast entry sets leverage for you before it places the order.

Margin and position mode#

set_margin_mode and set_position_mode exist as capability names and in the models (MarginMode, PositionSide), but they are not methods on the trait today. Configure margin mode and hedge/one-way mode on the exchange side.
