What TAMM means

The trade behind the instruction is being corrected where it was executed or cleared, for example a price or quantity correction, and settlement waits until the amended trade is available.

TAMM is a pending reason only (PEND); it is not in the failing reason list in MT or MX.

When you see it

  • On exchange or cleared trades shortly after execution, in markets where the trade feed drives settlement.

What to do next

  • Check with the executing broker what is being amended and whether your instruction must change to match the amended trade.
