Position Sizing

Position sizing is how you survive. The goal: risk a small, consistent percentage of capital per trade so that no single loss can cripple your account.

Prerequisites

No dependencies required. Works with manually provided prices. Enhanced with Groww MCP (live price, ATR, portfolio) or yfinance (pip install yfinance).

Data Needed

1. Account size: Total trading capital (ask user if not known)
2. Current price: get_quotes_and_depth from Groww, or user-provided
3. ATR(14): get_historical_technical_indicators from Groww, or calculate from candle data
4. Existing positions: get_equity_portfolio_holdings to check concentration (optional)

Method 1: Fixed Fractional (Default)

This is the go-to method. Simple, robust, works for everyone.
