The best entries aren't one signal — they're a stack of them landing in the same tiny zone. Two names for the highest-conviction stacks:
Inversion FVG. A fair value gap that price traded through instead of respecting — so it inverts. A bullish FVG that gets violated becomes resistance on the retest (and vice versa). Like a breaker, it's a failed level that flips, and it's a strong continuation/reversal signal precisely because the obvious expectation failed.
The 'unicorn'. When a breaker block and a fair value gap overlap at the same price, you get what ICT traders call a unicorn — a rare, high-probability confluence. Two independent reasons for the level to hold, in one spot.
The lesson underneath the jargon: a single order block is fine; an order block inside a fair value gap, in discount, after a liquidity sweep, in a killzone is an A+ setup. Each layer isn't just "one more thing" — it's another independent reason the trade should work. That stacking is exactly what TradeFern's grade measures. The next modules add the last two layers: where in the range and when.
