The Relative Strength Index measures how fast and how far price has moved recently — a 0-100 scale used here to avoid buying into an already-exhausted move.
RSI (Relative Strength Index) compares the size of recent gains to recent losses over a set window (14 periods here) and expresses it as a number from 0 to 100. High RSI (typically above 65-70) suggests a lot of recent buying pressure — potentially "overbought." Low RSI (below 30-35) suggests heavy recent selling — potentially "oversold." It doesn't predict direction on its own; it measures exhaustion.
The strategy was leaning bearish on GBPUSDm at this moment, but RSI at 32.4 was already deep into oversold territory — selling into that is exactly the kind of exhausted-move entry the filter exists to avoid.
This account uses RSI as a filter, not a trigger. A bullish trend alignment (EMA 50 above EMA 200) only converts into an actual BUY if RSI is in a healthy 40-65 range — not already overbought. If RSI has gone extreme in the direction the strategy would trade, the system holds instead, specifically to avoid entering right as a move runs out of steam.
