# Choosing strikes expiries and trade plans

Good options trading is not just choosing direction. It is choosing the right structure for a specific thesis, time horizon, and risk budget.

This page explains how to turn a market view into a trade plan.

## QUICK ANSWER

* choose structure first from the market view, then choose strike and expiry to match the expected move and time horizon
* nearer strikes are usually more responsive, while further strikes are cheaper but require larger moves
* shorter expiries are cheaper but harsher on timing, while longer expiries cost more but give the thesis more time
* on Callput, good strike and expiry selection should also account for premium or collateral path, request-based execution, and the close-versus-settle decision

## HOW DO YOU CHOOSE STRIKE AND EXPIRY?

## Start with the thesis, not with the chain screen

Before choosing any strike or expiry, define the trade in plain language.

You should be able to say:

* what I think will happen
* by when I think it will happen
* how large I think the move can be
* what I am willing to lose if I am wrong

If those points are unclear, strike selection becomes guesswork.

### Classify the market view

Most option structures start from one of four broad views.

| Market view      | Typical structures              |
| ---------------- | ------------------------------- |
| Mildly bullish   | `Sell Put`, `Sell Put Spread`   |
| Strongly bullish | `Buy Call`, `Buy Call Spread`   |
| Mildly bearish   | `Sell Call`, `Sell Call Spread` |
| Strongly bearish | `Buy Put`, `Buy Put Spread`     |

The key is not just direction. It is also the expected magnitude of the move.
{% endstep %}

{% step %}

### Decide whether the move is bounded or open-ended

This is where many traders improve rapidly.

Ask:

* do I expect a huge move if I am right
* or do I expect a more contained move into a target zone

If the move is open-ended:

* long single-leg options may be more appropriate

If the move is bounded:

* vertical spreads are often better

This one decision often matters more than whether you choose a call or a put.
{% endstep %}

{% step %}

### Choose strike based on responsiveness versus convexity

Strike choice is always a trade-off.

#### Closer-to-money strikes

These usually offer:

* higher premium
* higher delta
* more immediate responsiveness
* less reliance on an extreme move

#### Further-out-of-the-money strikes

These usually offer:

* lower premium
* lower delta
* more convexity if a large move happens
* a higher chance of expiring worthless

Cheap premium is not the same as a good trade. Sometimes the option is cheap because it is unlikely to matter.
{% endstep %}

{% step %}

### Choose expiry based on thesis horizon

Expiry should match the time horizon of the catalyst or market regime.

| Expiry choice | Strength                                                             | Weakness                                                 |
| ------------- | -------------------------------------------------------------------- | -------------------------------------------------------- |
| Short-dated   | lower upfront premium, stronger convexity around immediate catalysts | harsher theta, more timing risk                          |
| Longer-dated  | more time for thesis to play out, less concentrated theta            | higher premium, slower payoff response in some scenarios |

If the thesis is about a near-term catalyst, a short expiry may fit.

If the thesis is about a slower directional shift, a longer expiry is often cleaner.
{% endstep %}

{% step %}

### Decide whether volatility is helping or hurting

Options are not only about price direction.

You should also ask:

* am I buying volatility or selling it
* does implied volatility look rich or cheap relative to the scenario I expect

Broadly:

* long options prefer enough movement to justify premium
* short options prefer movement to stay contained
* spreads can reduce pure volatility dependence by bounding the payoff

If you ignore implied volatility, you may choose the correct direction and still choose the wrong structure.
{% endstep %}

{% step %}

### Match structure to constraints

Every trader operates under practical constraints.

Common examples:

* limited premium budget
* limited collateral budget
* need for defined max loss
* need for convex upside
* discomfort with uncapped single-short exposure

Use those constraints to narrow the structure.

| Constraint                                      | Usually pushes you toward         |
| ----------------------------------------------- | --------------------------------- |
| Need limited initial loss                       | long call, long put, debit spread |
| Need defined risk on premium-selling idea       | credit spread                     |
| Need lower premium than outright long option    | debit spread                      |
| Need lower tail risk than a single short option | credit spread                     |
| {% endstep %}                                   |                                   |

### Write the trade plan before entry

Every option trade should have a written plan, even if it is short.

At minimum, document:

1. thesis
2. structure
3. underlying, strike, and expiry
4. max loss
5. target scenario
6. invalidation scenario
7. intended exit path before expiry
8. settlement plan if the trade remains open near expiry

This is especially important because options can change quickly as time and volatility shift.
{% endstep %}
{% endstepper %}

## A practical decision tree

Use this simple structure-selection flow:

1. Am I bullish or bearish?
2. Is the move likely to be large or contained?
3. Do I want to pay premium or collect it?
4. Do I need defined loss?
5. Can I accept capped upside if the trade becomes more capital efficient?

Typical outcomes:

* large bullish move, limited risk needed -> long call
* large bearish move, limited risk needed -> long put
* bullish with bounded upside target -> buy call spread
* bearish with bounded downside target -> buy put spread
* mildly bullish, willing to collect premium with defined risk -> sell put spread
* mildly bearish, willing to collect premium with defined risk -> sell call spread

## What professionals often do differently

Experienced traders do not simply ask, "What is my direction?"

They ask:

* what must happen for this structure to outperform alternatives
* what am I implicitly assuming about volatility
* what path hurts this trade even if my directional idea is partly right
* is there a spread that expresses the same thesis with better efficiency

That mindset is one of the biggest upgrades from beginner to intermediate options trading.

## How this maps to Callput

On Callput, structure selection matters even more because the product surface is focused on:

* single-leg calls and puts
* vertical spreads

That means the quality of the trade often comes down to:

* choosing the right strike
* choosing the right expiry
* deciding whether a single-leg or a spread is the cleaner expression
