My track record for EV CHARGE stocks. I have timestamps + buy fills for everything. This is the result of ONLY buying when H% is low. The result speaks for itself. It's a simple strategy. Learn what "HEAVINESS %" by Algos. Next, will also trade $DCFC + $NVVE + $BEEM + $HYLN

$HYLN ….HAVE PATIENCE. Over time this will grow….

alwaysinvesting1 posted at 2023-06-21T12:28:15Z

$HYLN still under $2 I see. Buy them up people. HYLN will win the NG trucking war. The others can’t compare. Lots of haters in here. I just block them. It takes time and money to build a behemoth. We are about 8 years into this company (and three as a publicly traded company), and when they finally remove the “SPAC STINCH” and show growth you will all wish you bought more at these levels…(we always do right)? It’s coming. Patience is what you young birds need to learn. We have been spoiled over the last 2 .5 years where stocks fly overnight. But the real truth still holds
