Setup, Strategy, System — Three Words, Three Scopes, and No Agreed Definition
Key takeaway
- The three words differ by scope, not by quality. A setup is one specific trigger; a strategy is the broader approach that trigger belongs to; a system is a strategy with the discretion removed.
- There is no standard definition — the video says so outright, and it disagrees with other well-argued definitions of the same words. Treat any of them as a local convention, not a fact.
- This matters exactly when precision matters: automating something, writing rules down, or copying another trader. Everywhere else it is a vocabulary question, and the video is honest enough to say so.

A short answer to a question that keeps getting asked
This is one trader at a whiteboard giving his own usage, explicitly labelled as his own: "this is just my take on it, some people use these all exactly the same things."
That framing is the reason to read it. Most content that defines trading vocabulary presents a definition as if it were the definition. This one opens by conceding that in common use the three words are interchangeable, then explains the distinctions he draws anyway — and invites disagreement in the comments.
A setup is the specific thing on the chart
"A setup is something specific on the charts, or on the tape if you're tape reading, or fundamental, that will make you take the trade." His example: price is in a range, and you buy the break out of it.
This is the granular end. A setup names a shape and a trigger — a double top you sell, a failed high you fade, a range break you buy. It can carry filters (only in this direction, only on this timeframe), but it stays one identifiable pattern.
The scope test is simple: if you could point at a single chart and say there it is, it is a setup.
A strategy is the category the setup belongs to
"A strategy is going to be: listen, I have a strategy where I'm buying breakouts, I'm buying volatility expansion. It's a bit broader."
The examples he gives for a mean-reversion strategy are selling a double top, fading a failed high, and shorting a head and shoulders. Three different chart shapes, one thesis. That is the relationship: a strategy is a thesis, and setups are the ways you express it.
This nesting is worth more than the definition. If you cannot say which thesis your setup expresses, you have a pattern you learned rather than a reason to trade it — and patterns without a thesis are the ones you abandon the first time three of them fail in a row.
A system, in his usage, is the version with no room to negotiate
"Whenever someone says 'I've got a system', I always think there's no element for discretion there... it's very robotic. There's no room for trader input."
His example is a moving-average crossover: buy when the 5-period crosses above the 20, sell when it crosses back below, with matching rules for managing the position. "It's purely mechanical and I always do it... there's no room for negotiation with it."
So on this reading, system and strategy sit at a similar scope, and what separates them is not size but whether a human gets a vote at execution time. He notes his own preference is a mix: mostly systematic, with some discretion on top.
| Word | Scope | What it fixes |
|---|---|---|
| Setup | One pattern on one chart | When you pull the trigger |
| Strategy | A family of setups sharing a thesis | Why any of them should work |
| System | A strategy with the discretion removed | Whether you get to overrule it |
The definitions are not standard, and that is the actual finding
These are not the only defensible definitions of these words, and the differences are not cosmetic — they lead to different advice.
Compare this with the definition in trading system vs strategy, which argues a system is the fixed sequence of steps you take on every trade — market selection, opportunity, size, entry, exit — and a strategy is the variable method you use to satisfy one of those steps. On that reading, a system is bigger than a strategy and says nothing about discretion. On this reading, a system is roughly the same size as a strategy and is defined entirely by the absence of discretion.
System = mechanical (this video)
- Same scope as a strategy
- Defined by having no discretion
- "I have a system" means it is automatable
System = the whole process (the other reading)
- Wider than a strategy
- Defined by fixed, ordered steps
- "I have a system" means faults are locatable
Neither is wrong. But if you read one definition and then take advice written under the other, you will end up building the wrong thing — chasing full automation when what you needed was a written process, or writing a process when what you needed was to stop overriding your own rules.
What the video does not do
It is a vocabulary video, and it stays inside its lane. Two things you should not expect from it.
First: none of the three words implies an edge. You can nest three setups inside a clearly named strategy, mechanise the whole thing, and still lose money. The vocabulary organises what you do; it says nothing about whether what you do has positive expectancy. That has to be measured separately — see cutting losses and position sizing for the arithmetic side of it.
Second: it never says which end of the discretion scale you should be on. He mentions his own mix and moves on. That is a real question with a real answer for a beginner, and it is argued properly elsewhere: less experience means less discretion, because discretion needs emotional neutrality you do not have yet. That case is made in full in what a complete trading system actually requires.
What it does give you is a scope ladder you can apply to your own notes in about ten minutes, and permission to stop treating the words as if they had fixed meanings. Both are worth the eight minutes it runs.
Try this week
- Write down the last five trades you took. For each one, name the setup in five words or fewer.
- Group those setups. If two or more express the same underlying bet, you have found a strategy — name it.
- For any setup that does not group with anything, write the thesis it expresses. If you cannot, that is a pattern you copied rather than a trade you understand.
- Mark each rule you follow as mechanical or discretionary. Count how many times last month you overrode a mechanical one.
- Next time someone shares "their system", ask whether they can override it and when they last did, before you copy anything.
Common questions
What is the difference between a trading setup and a trading strategy?
A setup is one specific, identifiable trigger on the chart — a range break you buy, a double top you sell. A strategy is the broader approach that setup belongs to, such as trading mean reversion or trading volatility expansion. One strategy usually contains several setups, which are different chart expressions of the same underlying bet. The test is whether you could point at a single chart and say "there it is": if yes, it is a setup.
Is a trading system the same as a trading strategy?
It depends who you ask, and there is no standard. In this video a system is a strategy with the discretion taken out — purely mechanical rules such as buy when the 5-period moving average crosses above the 20, with no room for judgement at execution. Other traders define a system as the entire fixed sequence of steps around a trade, which makes it wider than a strategy and unrelated to discretion. Both definitions are in common use, so ask which one someone means before copying their approach.
Does it matter which word I use?
Mostly not. It matters when precision matters: writing your rules down, having an indicator or signal coded for you, or trying to copy what another trader does. In those situations, an ambiguous word produces the wrong build. In ordinary conversation the three are used interchangeably and nothing is lost.
Should a beginner trade mechanically or with discretion?
This video states a personal preference for a mix and does not argue the case. The stronger argument made elsewhere is that discretion requires emotional neutrality, which takes years to develop, so a beginner should mechanise as much as possible and leave judgement only where the rules genuinely cannot reach — typically the read on overall market direction.
How many setups should one strategy contain?
The video does not put a number on it, and neither should you at first. The useful constraint is not the count but the grouping: every setup inside a strategy should express the same thesis. A setup that does not group with anything is usually a pattern picked up from somewhere rather than a trade with a reason behind it, and those are the first ones abandoned when a losing run starts.
