These price levels follow a strong logic. There are generally two barriers near each major round-number level. For example, 87 and 96 are the two barriers below 100. So when the price moves toward 100 from below 60, it will stall in the 87–96 range. Once it breaks through, the 100–150 range opens up. The two barriers above 100 are 114 and 124. When the price rebounds to these levels, it will usually retest 100 to see whether it can hold. If it cannot, it will seek support at 96 or 87 (occasionally dipping as low as 84–82 in a sharp wick). In short, 100 is not truly established as support until the price moves above 127. Take SOL, for example: the monthly Bollinger Bands middle line is right between 124 and 127. If the price gets above this zone, a bull market surge begins; if it fails, it will retest 100–96 to consolidate before moving higher.

Likewise, 150 is a secondary round-number level. Its barriers below are 144 and 147, and its barriers above are 154 and 157. So the first rebound from below into this area will inevitably stall and pull back.

Both SOL and MSTR follow this pattern of advances and pullbacks. So when taking profits on long or short positions, avoid these barrier levels and exit a little early.

This pattern applies to all assets in both the stock and crypto markets.
