🌅 Watchlist part 1 ✅ $AZI mid $0.50 support, if above $0.75, have potential to $0.90 / $1.20 ✅ $RLMD low $6 support, if above $6.50, have potential to $7 / $7.40 ✅ $SAFX low $0.30 support, if above $0.40, have potential to $0.50 / $0.60 ✅ $EONR $0.80 support, if above $1, have potential to $1.20 / $1.40 ✅ $ATRA low $5 support, if above $5.50, have potential to $5.80 / $6.30 ⚠️ The above tickers are not ideal for swing accumulation at current price ⚠️ ✅ Ideal long entry near low current support 🎯 Ideal stop loss if below current support ⚠️ Avoid chasing long into strength near resistance. 🎯🎯 Goal is GR🤑🤑N not GR🥵🥵D
