VOLUME & MONEY FLOW
Force index
The power behind a move — direction, size and volume in one number.
spec id: filength (default 13)
What does Force index measure?
The power behind a move — direction, size and volume in one number. Big positive spikes mean buyers arrived in force.
How is Force index calculated?
Take today's close minus yesterday's close, multiply by today's volume, and smooth the result with a 13-candle exponential average.
Written by reading the engine’s real computation, not a textbook — where the two differ, the page describes what actually runs.
How do I use Force index in a bot?
In the builder, add an indicator of type fi (parameters: length, default 13). Its value becomes an operand you can compare in any entry or exit rule. The engine grades the whole rule honestly: real fills, no look-ahead, half the history held back.
