Following 50 oil is to make it convenient for everyone to see the position. Don't heavily invest, my friends. The heavier the investment, the more I can't let go. For example, last night this vine originally had a 100 oil position with a profit of 300 oil, but I didn't exit. A normal position of 300 would have reached 800, and I probably would have exited. This is roughly how it affects things, so those who know me can just follow with 50 oil to see my position situation.
