Returns a TransactionInstruction that collects accrued interest and transfers it to the trader’s SY token account.

​
How It Works

YT held in open orders continuously accrues yield. Interest is staged automatically during order fills and removals — you don’t need to trigger staging manually. This instruction transfers the staged SY from your escrow to your token account. Staged interest is tracked separately from your trading balances (PT, YT, SY). To withdraw trading balances, use ixWrapperWithdrawFunds.
