Why you should know this
Fee labels depend on whether an order adds or removes liquidity, and lower fees can still accompany poor fills or inventory losses.
This is not about being told which trade to take. We are learning how to inspect the mechanism together, so a later decision is more deliberate and reviewable.
The short answer
This lesson turns the mechanic into a pre-trade execution check covering price control, cost, fill risk and the reader’s next action.
Taker: removing available liquidity
A taker order matches resting orders immediately and removes displayed liquidity.
A market order is normally taker. A limit order can also be taker if it crosses the spread. With a ₱101 ask, a buy limit at ₱102 can execute immediately against asks. Its price boundary is ₱102, but its liquidity role is taker.
Order type and fee role are related, not identical.
Basic fee calculation
A simplified trading fee is:
Executed notional × Fee rate = Trading fee
Suppose a fictional ₱50,000 execution has a 0.20% taker fee:
₱50,000 × 0.002 = ₱100
At a fictional 0.10% maker fee:
₱50,000 × 0.001 = ₱50
The visible difference is ₱50. Whether waiting for maker execution was better depends on the fill, market movement, spread and opportunity cost.
The maker’s hidden cost: adverse selection
A resting buy order may fill when informed or urgent sellers arrive because price is about to fall. A resting sell may fill just before price rises.
The maker saved a fee but acquired an unfavorable position. This is adverse selection: execution occurs when the other side may have an advantage.
Fee savings must be compared with post-fill price movement, inventory and hedging cost.
The MAKER check
- M — Marketability: will the order cross now?
- A — Adverse selection: why might the other side choose to trade with it?
- K — Queue: how much rests ahead?
- E — Eligibility: which current fee or reward conditions apply?
- R — Result: net execution after price movement and all costs?
This moves the conversation from “What fee did I pay?” to “What result did I obtain?”
Common mistakes
- Assuming every limit order is maker.
- Comparing fee percentages without comparing fill prices.
- Treating a rebate as guaranteed income.
- Ignoring mixed maker/taker treatment on partial execution.
- Using another user’s tier or an old screenshot.
- Chasing maker status when completion matters.
- Ignoring inventory, adverse selection and final PHP costs.
A familiar Philippine or Asian example
A learner in the Philippines studies a fictional crypto quote and writes the pair direction, intended action, price control, estimated cost, possible fill problem and exit plan. The exercise uses paper values only. No order is placed.
One risk or limitation
Examples simplify execution. Real venues differ in order logic, trigger source, fees, tick and lot sizes, available liquidity and outage handling. A checklist can reduce avoidable mistakes, but it cannot guarantee a price, fill, exit or profit.
How this connects to market mastery
Market mastery includes execution discipline. A strong market view can still fail when the pair, order type, size, liquidity, fee or exit mechanics are misunderstood.
Quick check — no money needed
Use a fictional quote. Write the pair, buy or sell action, order type, price control, size, estimated fees, liquidity concern and the condition that would cancel the plan. Then explain which field protects you from the largest avoidable mistake.
If you can explain your answer and name the main limitation, this lesson is complete.
