While signals can be based on the same formulas as indicators, signal calculations are substantially more complex and take in to into account a far greater number of factors, such as trading costs, order generation priorities, and strategy performance measurements, that affect market entry and exit conditions.

Signal logic can make assumptions about price movement within bars that allow appropriate market entry and exit points to be determined when intra-bar data is not available. Signals compile strategy performance data and support backtesting and Automated Trade Execution.
