xStock vs NYSE
Triple tape
Pyth sets the cash session. The desk then compares NYSE, the xStock DEX, and Ondo when that feed exists. Buy the discount, sell the premium, LP only when they agree.
Overnight board — cheapest first

This is the after-hours book. Names at the top are the ones the DEX is giving you cheaper than cash.
Trade the tape
Arm desk uses your deposited USDC on MarkFill. The site wallet signs the fill. You do not approve each trade. Deposit on the Account tab first. “From my wallet” still needs a signature.
Your MarkFill wallet
This address is only yours and does not change after it is created. Send USDC and a little SOL for fees. Export the key to import it in Phantom/Jupiter if you want full control.
What you bought
Withdraw to main wallet
Withdrawals go back to the connected wallet. Put a little SOL on your MarkFill address for fees.
Session LP
NYSE open → tight bins. Overnight fair → wider bins. Off-tape → no LP.
Fair-print receipts
Each fill stores NYSE, on-chain, bps, and session at send time. That is the proof the gate did work.
