Brokerage Order Fill Review Checklist

A brokerage order fill review checklist helps traders study what actually happened after an order executed. The fill price is only one line. The better review asks what the bid and ask looked like, what order type was used, whether liquidity was thin, and whether the result matched the written plan.

Educational note: this is a process framework, not personal tax, legal, trading, or investing guidance.

The simple framework

• ▸Record the intended entry or exit rule before judging the fill.
• ▸Compare fill price with bid, ask, midpoint, and last price when available.
• ▸Separate market movement from order-choice error.
• ▸Note time of day, spread width, volatility, and liquidity.
• ▸Review broker-specific records using current account statements and confirmations.

Example math

Suppose a stock shows a bid of $49.95 and an ask of $50.05. The spread is $0.10. A 100-share market order fills at $50.06 during a fast move. Compared with the midpoint of $50.00, the fill is $0.06 worse, or $6 on 100 shares.

That $6 may be normal in a fast market, or it may show that the order type did not match the liquidity. The checklist is not there to complain about every penny. It is there to find repeatable patterns that can be improved.

What to write down

• ▸Ticker, order type, side, quantity, and timestamp.
• ▸Intended price zone or invalidation level.
• ▸Bid, ask, midpoint, last price, and fill price if available.
• ▸Spread width and estimated slippage.
• ▸Whether the fill changed the trade thesis, risk, or exit plan.
• ▸Screenshot, statement, or confirmation used as the source record.

Common mistakes

• ▸Judging a fill without recording the spread.
• ▸Blaming the broker when the order type was poorly matched to liquidity.
• ▸Ignoring time-of-day effects around open, close, news, or earnings.
• ▸Reviewing winners more generously than losers.
• ▸Skipping small slippage that repeats across many trades.

Bucko workflow

Use Bucko to keep order reviews connected to the trade journal, risk dashboard, and guardrail notes. TradingView can provide market context. Monko user-configured automation should keep order rules, caps, and kill-switch controls visible. Copy Trader workflows should include route notes, size caps, and audit trails so fills are reviewed as process data, not just outcomes.

Practical checklist

• ▸Save the order confirmation.
• ▸Write the bid, ask, midpoint, and fill.
• ▸Calculate slippage in dollars and percent.
• ▸Mark whether the order followed the plan.
• ▸Tag the fill by liquidity condition.
• ▸Review patterns after a sample of trades, not one emotional example.
