Wow, I increased the position to 60 and took half off at 85, then went down to increase the position to 30 and took half off at 70. Now the average price is 3650, small position... going down to increase again...
SUI is doing pretty well. I found that SUI's fluctuations are also easy to trade. The SUI daily chart is like this, not going up much, so it's quite suitable to go for a counter-trend short.
