How Doris Works

Doris is a Translation Engine that converts complex financial derivatives into simple visual shapes anyone can understand. Here is exactly how it works.

01

See the Shape

Every investment is visualized as a kinked line on a payoff chart. The horizontal axis shows what the market does. The vertical axis shows what happens to your money. No spreadsheets, no jargon - just a clear picture.

Under the hood: The kinked line is a payoff diagram - a well-established tool in quantitative finance. Doris makes it accessible by removing all the technical notation and replacing it with intuitive visual controls.

02

Set Your Safety Net

Use a simple slider to set your maximum loss. This becomes the flat bottom of your shape - no matter what happens in the market, your losses stop at the floor you set.

Under the hood: Behind the scenes, Doris calculates the optimal protective put option strike price, factoring in the full volatility surface, time to expiry, and current market conditions.

03

Choose Your Shape

Pick from our library of pre-designed shapes, each representing a different risk/reward profile. Conservative shields, balanced corridors, growth ramps, and more.

Under the hood: Each shape maps to a multi-leg options strategy. A 'Balanced Corridor' is a collar. A 'Safety Shield' is a protective put. A 'Growth Ramp' is a bull call spread. You never need to know this.

04

Invest with One Click

Tap invest and Doris handles everything. The Translation Engine converts your visual shape into a precise financial specification, the Structuring Optimizer finds the best execution, and the trade is placed.

Under the hood: The entire chain - from visual shape to Outcome Specification to multi-leg options order - executes in under 2 seconds via FIX protocol, with all legs placed simultaneously.

Design Principles

Visual First

Every interaction starts with a picture. If you cannot see it, you should not invest in it.

No Jargon

We never use words like 'call', 'put', 'strike', or 'Greeks'. Everything is translated to plain language.

Safety by Default

Every shape has a built-in safety net. You cannot create an investment without downside protection.

Universal Shapes

The same visual shapes work across equities, crypto, FX, and commodities. Learn once, invest anywhere.

Instant Feedback

Every slider change updates the shape in real time. You always see the impact of your decisions immediately.

Institutional Grade

Behind the simple interface is the same financial engineering used by the world's largest hedge funds.
