Previously, someone misunderstood the phrase 'welding the car door shut'. Let me reiterate. Viewing a crucial point as a car door and welding it shut does not mean it cannot break below; rather, our first line of defense (the action of reducing positions) should be set here. If it breaks below this point, we need to re-enter at important support levels below. If it does not break below this point, it will gradually become the bottom for the short to medium term, and we will incrementally push up to see how much space we can gain.

Currently, Sol has risen to test 206 again. It couldn't break through 206.50 last night, so the car door at 200 isn't welded shut. If it breaks through 206.50 today, it can be welded shut. Under normal circumstances, it won't break below this point again. The second line of defense for the bulls is set at 194.00. If this second line of defense is broken in the future, any long positions with an average cost above 194 should surrender. Here, we need to cut losses on the remaining positions and keep the losses within a manageable range.
