Inverse Prices

Sidepit's native price is the amount of Bitcoin paid for one U.S. dollar, expressed as integer satoshis per USD.

USD/BTC = 100,000,000 ÷ sats-per-USD

Sats per USD	Familiar USD per BTC
1,000	$100,000
1,250	$80,000
2,000	$50,000

The directions move opposite each other:

• a higher Sidepit price means a lower familiar USD/BTC price;

• a lower Sidepit price means a higher familiar USD/BTC price; and

• a Sidepit bar high is the familiar USD/BTC low for the same interval.

Linear satoshi P&L

For one contract, a one-tick move changes P&L by the contract's published tic_value in sats. If unit_size is $500 and the minimum tick is one sat per USD, one tick is worth 500 sats per contract.

Convert to familiar USD/BTC at the display edge. Keep order construction, matching, margin, and P&L reasoning in the exchange's native integer units to avoid double inversion or floating-point rounding.
