The band
Raydium concentrated pool, devnetBoth sides squeezed into one tight range, $24.09 to $30.05.
Pool price now
Below $24.09 this pool holds nothing to trade against, so a sell that tries to push under it is refused by the chain. The trade log shows the test.
Dollars in the pool
Includes the $55,999.00 we locked in to open this shape.
SHASH in the pool
Started at 1,950. Buys take tokens out, sells put them back.
Toll the token kept
Every SHASH transfer pays a 2.5% toll to the token itself ($55,998.85 plus 1,950 SHASH concentrated into one range). It sits on the pool account, outside the market, until the weekly sweep collects it.
Where the liquidity sits
$55,998.85 plus 1,950 SHASH concentrated into one rangeGold is tokens for sale, green is standing buy money. Faded means the side has been traded through.
Bars are computed from the recorded size of each position plus the live pool price, the same math the chain uses.
How this shape works
One two-sided position: 1,950 SHASH above the price and $55,998.85 below it, all inside a single range from $24.09 to $30.05. Inside the range it behaves like an extremely deep pool, because everything is concentrated where trading actually happens.
The payoff is execution: 500 tokens cost $14,123.31 here, the cheapest of all five shapes. Small trades barely move the price.
The price cannot leave the range in either direction. At the edges the pool simply runs out of inventory, and the chain refuses anything that would push past them.
Where it breaks
Both refusals, measured: the buy of 2,000 was refused because the asks ran out at $30.05, and the sell of 3,000 was refused at the $24.09 floor. A hard ceiling is a real cost: buyers who wanted more tokens were turned away.
The floor also sits below hardware parity: $24.09 is under the $27 mint price, so this exact configuration would let the token trade below the machines behind it. The range could be drawn higher, but then the ceiling bites sooner.
What it proves for SHASH
The best execution of any shape and a true hard floor, paid for with $56,000 of locked dollars and a ceiling that refused real buy demand at $30.05. A strong second choice if we ever want to spend capital on depth.
