Building an Option Strategy From Scratch, in the Order the Decisions Arrive
Most people acquire strategies rather than building them, which means the parts that determine the outcome were decided by somebody who knew nothing about their circumstances.
Building one is less difficult than it sounds, because the sequence is fixed and each step has a small number of reasonable answers.
Step One: Choose One Instrument
Attention divided across several contracts produces shallow preparation in all of them, and preparation depth is the binding constraint.
One liquid index contract is the standard starting point, and it can be understood properly within a month.
Step Two: Decide the Horizon
Whether positions resolve within a session or across days changes the contract, the levels and the management entirely.
Deciding this before anything else prevents the most common structural error, as options intraday tips sets out.
Step Three: Write the Entry Condition
Two or three conditions that must all be present, stated so plainly that another person could apply them identically.
Anything requiring a paragraph cannot be applied consistently and will produce a record that cannot be interpreted.
What Makes a Good Condition
It has to be observable rather than interpretive: a level tested, participation expanding, a time window reached.
Conditions involving judgements about how price feels are not conditions.
Step Four: Write the Invalidation
One sentence stating what would prove the idea wrong, expressed as a level on the underlying rather than as a premium value.
This is what makes sizing arithmetic possible and gives the exit a reason that exists before the position does.
Step Five: Choose the Contract Rules
Which expiry, how far from the money, and what depth is required before a strike is acceptable.
Writing these as rules rather than deciding each time removes a recurring source of variation.
Why Contract Rules Matter So Much
Expiry and strike change the position more than direction does, so a correct view in the wrong contract still loses.
Near the money and mid cycle is the default that survives most conditions, as index intraday tips describes.
Step Six: Derive the Sizing Rule
Accepted loss divided by the distance to invalidation gives the quantity, with total loss on the premium assumed rather than an orderly exit.
This converts sizing into arithmetic and removes the single largest source of damage in most accounts.
Step Seven: Specify the Losing Exit
Where the position is closed when the idea is wrong, placed in the market at the moment of entry.
An exit held only as an intention is abandoned in exactly the conditions it was written for.
Step Eight: Specify the Winning Exit
A consistent rule for taking gains matters more than which rule is chosen, because expectancy depends on a stable relationship between wins and losses.
Improvised exits on winning trades produce a record from which nothing can be learned.
Step Nine: Add a Time Limit
A window in which the expected move should appear, after which the position is closed regardless of price.
In a decaying instrument this is a structural requirement rather than a refinement.
Step Ten: Write the Exclusions
Contracts, hours and conditions under which the strategy does not trade, decided once and applied without argument.
The final sessions of a cycle and the minutes around scheduled announcements belong here for most strategies.
Step Eleven: Set the Session Limits
A maximum number of trades and a loss beyond which the day ends, both written when they cost nothing to accept.
Limits set during a difficult session are negotiated rather than written.
Step Twelve: Compute the Cost Filter
Brokerage, charges and spread expressed as the movement required, so that setups below that threshold are disqualified automatically.
Most strategies fail this test before any question of accuracy arises.
Step Thirteen: Decide the Sample Size
How many trades will be taken before the strategy is judged, agreed in advance and not adjusted afterwards.
Any workable method produces losing runs long enough to feel decisive, which is what this defends against.
Step Fourteen: Forward Test Without Money
Record what the rules would have produced, in real time, for the decided sample, before any capital is involved.
This reveals whether the strategy produces decisions at all and how many sessions actually qualify.
Step Fifteen: Trade It at Minimum Size
The first live positions exist to find where the process breaks under real conditions, as cheaply as possible.
Execution errors cluster here and have nothing to do with the strategy itself.
Step Sixteen: Record Everything
Contract, reason, level, entry time, invalidation, exit reason and whether the rules were followed, on every trade.
Without those fields no diagnosis is possible and every later adjustment is a guess.
Step Seventeen: Review at a Fixed Interval
Compliance first, then the numbers, then one written change with the sample over which it will be judged.
Reviews triggered by a bad run reach conclusions that match the mood, as intraday trading strategies sets out.
Step Eighteen: Change One Element at a Time
Adjusting entry, exit and sizing together makes the next period uninterpretable whatever happens.
One change, held for a full sample, is the only version that produces an answer.
What Not to Add
Indicators duplicating price information, additional instruments, extra legs and more frequent trading all add cost without addressing anything.
Every addition needs to justify itself against the record rather than against how it feels.
When to Abandon a Strategy
When the decided sample is complete, the rules were followed, and the result after realistic costs does not clear the alternative.
Abandoning mid-sample on the basis of discomfort is how workable methods get discarded.
When to Scale It Up
Only after full compliance across a complete sample, and then in small increments derived from the accepted loss.
Increases justified by a good month are increases justified by conditions.
The Strategy Is Half the Work
Preparation, records and review are the other half, and they determine whether the strategy is ever applied as written.
Traders who build a strategy and skip those produce a record describing something else entirely, as intraday tips for beginners describes.
Where the Capital Sits Throughout
A limited, ring-fenced portion decided in advance and not needed for anything else, with the rest arranged separately.
That separation is what makes an honest test possible, as investment advisory sets out.
Write the Whole Thing on One Page
A strategy that cannot be read in a minute will not be followed on a difficult morning, and complexity is abandoned precisely when structure is most needed.
Instrument, conditions, contract rules, sizing, both exits, exclusions and limits fit comfortably on a single sheet, as intraday tips sets out.
Expect the First Version to Be Wrong
The initial conditions will qualify too many sessions or too few, and the first sample exists to establish which of those is happening.
Treating version one as a draft rather than as a commitment makes the review considerably more honest.
Do Not Borrow Someone Else’s Numbers
Levels, sizes and limits copied from a course or a video were derived from circumstances that are not yours, particularly the capital and the hours.
The structure of a strategy can be borrowed and the numbers inside it have to be computed for your own situation.
Keep the Old Versions
A dated record of what the strategy said six months ago makes it obvious whether it has been improved deliberately or eroded gradually.
Most strategies are not abandoned; they are quietly rewritten one uncomfortable session at a time until nothing measurable remains.
Building It Is the Point
The value of this exercise is not the finished page but the process of discovering how many of these decisions you had never actually made.
Most people find three or four steps they had been improvising, and each one of those was quietly deciding outcomes without being examined.
FAQs
What comes first when building a strategy?
One instrument and a decided horizon. Both determine every subsequent choice.
How many entry conditions should there be?
Two or three, observable rather than interpretive, stated plainly enough that another person could apply them.
Where should the invalidation be expressed?
As a level on the underlying, not as a premium value, since premium moves for unrelated reasons.
How is size derived?
Accepted loss divided by the distance to invalidation, assuming total loss on the premium rather than an orderly exit.
Why decide the sample in advance?
Because every workable method produces losing runs long enough to feel decisive mid-sample.
When should the strategy be changed?
At the review, one element at a time, with a new sample over which the change will be judged.
When should it be abandoned?
After a complete sample with full compliance, if the result after realistic costs does not clear the alternative.
