Forex signal systems can create executions that are either manual or automated. A manual system involves a trader sitting at the computer screen, looking for signals and interpreting whether to buy or sell. An automated trading system involves the trader "teaching" the software what signals to look for and how to interpret them. Signals can come from other currency pairs, bond prices, commodity prices, and stock prices. For example, a day trader may have a signal that when a certain stock index trades through its 100 or 200-day moving average their signal says they should sell a particular currency pair.
