What is execution?
Execution is the process of turning a decision into actual orders and fills. It includes the order type, quantity, price conditions, cancellation rules and management of an open position. A sound market interpretation can still lead to a poor trade if the fill arrives too late, the risk has expanded or the exit cannot operate as assumed.
The first question is not “Did price eventually move my way?” It is “At the moment I acted, was the defined opportunity still available on terms my plan allowed?” That distinction makes execution review useful even when the trade happened to make money.
Know what your order asks the market to do
A marketable order prioritises interacting with available liquidity, subject to the actual order type and exchange protections. A limit order specifies a price boundary but can remain unfilled. A stop is activated by its defined trigger; what happens next depends on whether it becomes a limit order or another supported order type. CME documents these differences in Futures Order Types.
Do not assume the label in a platform tells the entire story. Check broker and exchange handling, partial fills, time-in-force, protection ranges and whether protective orders are held at the exchange, broker or locally. A disconnected screen and an exchange-held order are different operational situations.
A synthetic example: delay changes the trade
Use a fictional contract worth ten currency units per point. A plan proposes buying at 100.00 with invalidation at 99.00 and an objective at 102.00. Before costs, the planned risk is ten units per contract and the planned reward is twenty.
The condition occurs, but the decision is delayed. A marketable buy fills at 100.75. Keeping the same invalidation and objective now gives 17.50 units of price risk and 12.50 units of possible reward. The original picture on the chart has not changed, but the available trade has. Moving the stop closer merely to restore a pleasing ratio would create a different rule requiring its own justification.
Add two units of round-trip fees to this hypothetical example. A target fill would produce 10.50 units net, while an exit exactly at the stop would lose 19.50. Slippage could worsen the exit further. These are transparent arithmetic assumptions, not estimates of any particular instrument or broker.
Inactivity before a signal is different from delay after it
Waiting while your conditions are absent can be disciplined. Waiting after a valid trigger may reduce the remaining opportunity. A review should therefore record both when the condition became available and when the decision occurred. Measure delay from the defined trigger, not from the start of a chart or the first moment you felt interested.
Also record why you waited. Missing information, spread expansion, a nearby announcement or an entry outside your permitted window may justify standing aside. A no-trade decision is not automatically a mistake simply because the market later moved.
False comfort in simulated fills
A chart touching your limit price does not prove that your order would have filled. Queue position, available quantity and matching rules matter. Stops are not guaranteed loss caps; gaps, fast movement, exchange protections and outages can affect the result. The CME Market by Order explanation describes why order-level information differs from aggregated depth.
The decision exercises use fictional situations to rehearse reasoning. Written exercises do not reproduce broker routing, queue priority or live emotional pressure.
A pre-order and review framework
- Name the exact condition that permits action and the event that cancels it.
- Check whether the current entry still fits the intended invalidation and objective.
- Calculate quantity from the risk budget using verified contract values and costs.
- Confirm how the entry, stop and target behave if partially filled or disconnected.
- Afterward, compare intended prices with fills and explain each difference.
Do not practise live execution with money you cannot afford to lose, uncertain contract specifications or an unfamiliar order ticket. Use the calculators for arithmetic and the risk guide for exposure. The objective of execution work is repeatability under defined constraints, not a promise that precision removes market risk.
