$IRYS |Breaking through the 0.02 level
How should you understand support and resistance? Previous highs and lows are commonly used key price levels: the memory of price failing to rise above—or being supported at—a level can influence buying and selling when it returns there.
The first rebound after a level is lost is often seen as a test: if price is pushed back near that level, the case for support turning into resistance becomes stronger.
Don’t place orders during the fastest-moving minutes. Wait for the price to settle before deciding.

Just casual discussion—not advice.
