Forex signals are generated based on the analysis of market background, patterns, as well as indicators such as RSI, MACD, or the Fibonacci retracement. A more general signal should contain an entry-level (where to get in—buy/sell), an exit level (where to get out—to close the position), and a stop loss level (to minimize loss if the trade goes awry). Signals, as a rule, are sent in real-time, so the suppliers allow traders to make transactions almost simultaneously.
These signals reach traders through different platforms, including via short messaging service (SMS), email, or the Telegram application. Some of the platforms also come with alerts of the sort that can be configured to always look out for the best deals without fail. However, these are solely aimed at helping in the trading process, hence the need to provide a personal interpretation of the signals.
