CAPS Parser

A small Vue 3 + Vuetify tool for inspecting Pershing CAPS records. Paste lines from a CAPS file and each fixed-width field is split out and labeled, with its start/end column shown. Signed-overpunch numbers (quantity, price, fees, commissions, etc.) are decoded into readable values.

It handles record types 1, 2, 3 and 5. Lines with any other record type, such as the rarely used R4, are ignored.

Getting started

Requires Node.js 20.19 or newer.

git clone https://github.com/uclnj/caps-parser.git
cd caps-parser
npm install
npm run dev

Then open http://localhost:5173 in your browser.

Usage

1. Open a CAPS file in a text editor.
2. Copy the four lines that make up one trade: its 1, 2, 3 and 5 records.
3. Paste them into the Source Record box.

The fields below the box fill in as you paste or type. Each label shows the field name and its column range in the record, e.g. Account [22/31].

Building

npm run build     # outputs to dist/
npm run preview   # serves the built files locally

Claude was used to make sure there was nothing company related in this repo and to write the readme other than this part that I added.
