STFR means “Sell The Fucking Rip” when a price retraces in a downtrend, indicating that a short position should be adopted.
It is a trading mindset or strategy, particularly relevant in a strong downtrend or bear market. This means that when the price of a currency consistently resists uptrends but falls against the upward market trend, it is mostly a sell signal that should be deployed.
For instance, in STFR, when the market is fundamentally bearish, any short-term movement can be seen as a gift to enter or add to the short positions at a better price rather than a sign of a reversal.
When traders are buying into a trade because of FOMO, it is rather a time to STFR; hence, in a strong bear market with strong resistance, rips or sells are gifts.
