Who
Who is on the other side of your trade?
You cannot know, and you do not need to. The counterparty could be a fund that just got stopped out, a head-fake before aggressive buyers, or several large players acting on the same idea at different moments. Auction theory guarantees someone takes the other side. Your only job is to align with a large participant who likely shares your direction, then manage your own risk.
When I started, I imagined the market as one big institution with a single intention. It is not that. It is many large participants with different biases, and you will never know who is acting or why. Trying to theorize the counterparty is wasted energy.
So the question of who collapses to you. You read the order-flow signals, build a thesis that size is leaning your way, ride those coattails, and protect yourself if you are wrong. The market does not care about your position, which is exactly why your own risk is the only part of the who that you control.
What
What is order flow actually telling you?
Order flow is the what: the record of aggression and absorption at each traded price. A footprint chart shows who is lifting offers, who is hitting bids, where imbalance prints, and where one side is being absorbed. It tells you how the auction is being transacted right now. On its own, though, it is only half the read.
The signals are concrete: stacked bid and ask imbalance, delta fighting the close, repeated aggression that fails to move price (absorption). Those describe behavior. They do not, by themselves, tell you whether the behavior matters.
That is the trap most traders fall into, reading every print as a signal. The fix is to treat order flow as the what and refuse to act on it until you know the where.
Where
Where does the signal matter?
A signal is meaningless without location. Volume profile and key levels give you the where: value area, point of control, prior-day and overnight extremes, and low-volume nodes. The same order-flow signal can mean opposite things depending on where it happens, which is why context comes before the trigger.
Picture absorbed sellers at the prior-day high while today's value is migrating up and the open already held the overnight low. That context says buyers are strong, and the absorption supports a push higher. Now picture the same absorbed sellers at the prior-day low after a failed move up, with today's value below yesterday's. Same signal, different location, and now it is a short.
The order flow did not change. The where changed, so the story changed. That is the whole thesis: context first, trigger second.
When
When are you trading, and should you be at all?
Timing is its own edge and its own risk. The opening 30 minutes does not trade like midday, and the pre-market does not trade like either. Scheduled news and unexpected headlines can make your context irrelevant in seconds. For funded-account traders, when is also a rules question, because many prop firms restrict trading around news events.
A clean read can be undone by a release you did not have on your calendar. So the when works two ways. It shapes what kind of trade is even available, and it can void a thesis mid-trade. Knowing the session and the schedule is part of the setup, not an afterthought.
Key levels such as session boundaries and the opening range help you frame the session, and disciplined sizing keeps you safe through volatile windows.
Why
Why take the trade?
The why is the thesis that emerges when where, what, and when line up. It is not a feeling. It is a specific claim: a large participant likely shares my direction, at a level that matters, right now. If you cannot state the why in one sentence, there is no trade yet.
This is where the framework pays off. The why is not a separate indicator. It is the product of the other questions answered honestly. When the location is meaningful, the order flow confirms sponsorship, and the timing is appropriate, the reason to act writes itself.
Just as important, knowing the why tells you what would invalidate it. A thesis you can state is a thesis you can risk-manage.
How
How do you size the trade and survive?
How is risk management, and for funded traders it is the most important question of the six. Risk discipline is what lets an edge compound long enough to matter. A prop evaluation hands you the buying power of a Formula 1 car with a Camry's margin for error. That is not because anyone is out to get you. It is how firms compete for new traders. Your job is to drive the Camry on purpose.
Here is the math that keeps accounts alive. If your account allows a $1,000 max loss, structure your day so you risk on the order of $100. Then it takes a long, genuinely bad run to fail. If you actually lose ten days in a row at that size, the problem is the system, and the answer is to go back and reanalyze it, not to trade bigger.
A risk tool that sizes every position from a fixed max-dollar rule removes the in-the-moment math and keeps your risk identical trade to trade. That consistency, not a louder signal, is what separates traders who survive evaluations from traders who reset them.
