Market Order
An instruction to buy or sell immediately at the best available price. Market orders guarantee execution but not price — in fast markets or thin books the fill can be meaningfully worse than the last quote. Systematic strategies use them when certainty of position matters more than the last few cents.

Backtests are hypothetical, computed by DeployQuant's engine on minute-resolution consolidated US market data (2021-01-04 to 2026-07-17, $10,000 starting capital, no margin, fees and slippage not modeled) and do not guarantee future results.
