Recently, I’ve been researching some techniques to determine whether the market has truly bottomed out, and I found that looking at multiple dimensions together is more reliable.

First, regarding open interest, OI in the bottom area often drops to a very low level, which is an important signal. Also, keep a close eye on the weekly chart. For a true bottom reversal, trading volume needs to spike to at least about 8.5 times the daily average to be convincing.

There’s another easily overlooked point—the sustainability of capital accumulation. If the price keeps oscillating in a certain range but the capital buildup hasn’t even reached 1 billion, it’s probably not solid enough yet. Market bottoms can’t be confirmed in just a day or two; there must be enough turnover of chips and accumulation of funds.
