A plain-language introduction to signals, strategy logic, execution, and the controls around an automated trading system.
Algo trading, simply explained
Algorithmic trading uses software to monitor market information and create or manage orders according to predefined rules. Those rules might use price, volume, indicators, time, portfolio exposure, or external signals.
