Commission shopping is the wrong first filter for a futures order

The ticket is not the trade

A commission-filter uses posted ticket cost as the first screen when choosing who places an order and how closely it is watched. Full-service and broker-assisted desks are described as combining order placement, market guidance, and margin-call handling, at a higher commission than unassisted routing. The column treats that extra commission as potentially smaller than the implementation-cost of placement errors a supervised desk is meant to catch.

Implementation-cost is the extra paid or lost from a thin listing, a mis-keyed side, or an unexit-able lock, beyond the posted commission. The posted fee is only the visible line on the ticket.

Unassisted routing still has homework

Self-directed online placement is framed as a commission-saving path that still requires knowledge of symbols, listed months, and risk calculation, plus the ability to avoid impulsive extra trades. Discount online service is reserved for traders who can operate with little help from the firm.

Recurring placement errors listed include the wrong year or month, the opposite side, ignored session hours, and mixing up stop-order and limit-order instructions. Order-routing is selecting the contract, expiration, side, and instruction type that the venue will actually accept. A stop-order becomes executable only after a trigger price is reached. A limit-order will not trade worse than a stated price and may not trade at all.

Volume is part of the ticket

Routing a single contract into the thinner domestic sugar listing rather than the more active world listing is described as a liquidity mistake that can cost several hundred dollars. On the observation day, March world sugar volume was nearly 37,000 contracts versus five contracts in same-month domestic sugar.

A liquidity-filter checks traded volume and book depth before sending size into a listing. The archive presents the two sugar listings as the same month with very different activity, and the thinner one as the costly routing choice.

A lock can accept the short and refuse the buy

When a market is locked limit-up, a sell may still be accepted while a buy cannot. A short initiated into that limit-lock can remain open into the next session if prices continue higher.

The archive is not forecasting the next session. It is showing that a limit-lock can leave a newly opened short without a buy that the venue will accept.
