Options Analysis: Model a Multi-Leg Structure Before You Place It

Options Analysis is the manual side of Arthalab: build a multi-leg structure against the live option chain, see exactly what it would pay, and execute it when you are satisfied. It answers a different question from the strategy builder, and most traders end up using both.

Analysis and automation are different jobs

	Options Analysis	Option Strategy Builder
The question	What would this specific trade do, right now?	How do I run this rule every day without me?
Strike selection	You pick, against the live chain	A rule evaluated at execution time
Execution	You press execute, once	The engine, on its own schedule
Repeats daily	No	Yes, that is the point
Backtesting	Not its purpose	Core to it
Suits	A considered one-off position	A repeatable strategy

If you place the same structure most days, that belongs in the strategy builder where it can run without you. If you are constructing a position for today's specific conditions, that is what Options Analysis is for.

What the screen shows

Three things sit together, which is the point — reading them separately is where mistakes come from.

The live option chain

Strikes with open interest, volume, implied volatility and the bid-ask spread. Reading the chain properly covers what each column does and does not tell you; the short version is that volume and spread decide your execution while OI describes positioning.

The payoff

Build your legs and the payoff curve shows the result across index levels, with maximum profit, maximum loss and the breakevens computed rather than estimated. For anything beyond two legs this is genuinely hard to do in your head, and the shape is usually more informative than the numbers.

The greeks

Net delta, gamma, theta and vega for the whole position rather than leg by leg. The Greeks guide covers what each one means; the net figures are what describe your actual exposure.

Why net figures matter more than per-leg ones

A four-leg structure has four sets of Greeks, and reading them individually tells you very little. Netted, they describe the position in one line.

An iron condor, for example, nets to small delta, negative gamma, positive theta and negative vega. Read that and the strategy explains itself: you are being paid time decay to carry exposure to movement and to rising volatility.

What the netting buys you

Seeing the net figures before you execute is the difference between knowing what you built and hoping it is what you intended.

Saving a structure

A structure you have built can be saved, reopened later and executed again. This matters for two reasons.

You can prepare in advance. Build the structure calmly, save it, and execute when conditions arrive rather than constructing it under time pressure.
You can keep a record. A saved structure is a record of what you intended, which is useful when reviewing what actually happened.

Saving is not deploying

Saved structures are separate from deployed strategies. Saving does not start anything, and nothing executes until you explicitly execute it.

What you need before you can execute

An active plan
A connected broker — with today's login completed, unless you are on XTS
A registered IP address, whitelisted with your broker
Sufficient margin for the structure, including its peak during assembly

All four are the same requirements that apply to any live order. The margin point is the one most likely to catch you on a multi-leg structure, because the requirement partway through assembly can exceed what the finished position needs.

A sensible workflow

Start from the chain, not the structure

Check volume and spread at the strikes you are considering. A theoretically ideal structure on strikes nobody trades is not ideal.

Build the legs

Side, option type, strike and quantity for each.

Read the payoff shape before the numbers

The shape tells you what kind of trade this is. The maximum figures tell you how much.

Check the net greeks

Confirm the exposure is what you intended, particularly the sign of gamma and vega.

Convert the maximum loss to rupees

At the size you intend. If that number is uncomfortable, change the structure rather than hoping.

Save it

Then execute when you are ready, rather than building and executing in one unbroken motion.

Reading a payoff chart properly

A payoff chart is the fastest way to understand a structure and the easiest to misread, because it answers a narrower question than it appears to.

The curve shows what the position is worth at expiry, across index levels. It does not show what it is worth today, tomorrow, or at any point before expiry.

The chart tells you	The chart does not tell you
Maximum profit and where it occurs	How likely any of it is
Maximum loss and where it occurs	What the position is worth before expiry
The breakevens	How the value moves as volatility changes
The shape of the trade	Whether the strikes are liquid enough to trade

Why the greeks sit beside it

The right-hand column is why the net greeks sit alongside the chart. The payoff describes the destination; the greeks describe the journey, and most positions are closed somewhere along the way rather than held to expiry.

Where it fits against paper trading

Options Analysis models a structure and executes it for real. It does not simulate.

If you want to watch a strategy behave without risking anything, that is paper trading, which runs through the strategy builder and needs no broker at all. Options Analysis is for positions you intend to actually hold.

What it is and is not for

Every execution is deliberate. Nothing repeats on its own, which is exactly what you want for a considered one-off position. Daily repetition belongs in the strategy builder, where it runs without you.
The payoff is an expiry view. Historical performance of an approach is what backtesting answers, and that lives alongside this in the builder.
It is marked Beta because it is under active development, with new capability landing regularly.
Execution needs a connected broker. Building and modelling a structure needs nothing — only placing real orders does.

The short version

Chain, payoff and greeks together, then execution — for a considered one-off position
Net greeks describe the position; per-leg figures rarely tell you what you need
Save a structure and execute later rather than building under time pressure
Convert maximum loss to rupees at your intended size before executing
Daily repetition belongs in the strategy builder, not here

The execution itself has more going on than a single button suggests. How execution, verification and rollback work covers what happens after you press it.

Frequently asked questions

What the position would be worth at expiry across index levels. It says nothing about the value before expiry, how likely any outcome is, or how the position reacts to volatility.

The payoff describes the destination and the greeks describe the journey. Most positions are closed before expiry, which is the part the chart does not cover.

Yes. Building and modelling is the analysis half and needs nothing from your broker. Only execution requires a connection, an active plan and margin.

Treat it as gross. Brokerage, charges and the spread you cross on every leg both ways come out of whatever the chart shows.

A screen that puts the live option chain, payoff modelling and net greeks together, and lets you execute the multi-leg structure you build. It is the manual counterpart to the automated strategy builder.

Options Analysis is for a considered one-off position you execute yourself. The builder is for a repeatable rule that runs every day without you, with backtesting and paper trading attached.

No. The payoff shows what the structure would do at expiry, not how the approach performed historically. Backtesting belongs to the strategy builder.

To execute, yes — along with an active plan, a registered IP and today's broker login. Building and modelling a structure is the analysis half; executing it is a live order like any other.

Yes. Saved structures can be reopened and executed later. Saving does not start anything on its own.

A multi-leg position's exposure is the sum of its legs with the right signs. Netted, it describes the trade in one line; individually, four sets of numbers rarely tell you what you need.

No. It executes real orders. Paper trading simulates them, runs through the strategy builder and needs no broker.

It is in active use and active development. The capability is real; specific details may change, which is worth knowing before building a critical workflow on any one of them.
