Position sizing for Indian equity and F&O trades: fixed-fractional risk sizing with round-trip costs included, ATR-based stops, F&O lot rounding and margin checks, MTF/intraday leverage adjustment, gap-through-stop and circuit risk, Kelly from a trade journal, and portfolio limits. risk.py also covers R:R, trailing stops and journal statistics. Use when the user asks: "how many shares should I buy", "position size for X", "how many lots of NIFTY", "how much to invest", "risk per trade…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Position Sizing
Sizing decides survival. Risk a small, fixed fraction of capital per trade so that a losing streak,
which will happen, is survivable.
## Calculator
```bash
# Equity, structure stop
python3 scripts/risk.py size --capital 500000 --risk-pct 1 --entry 1450 --stop 1410
# Equity, ATR stop + gap-risk check for a midcap
python3 scripts/risk.py size --capital 500000 --risk-pct 1 --entry 1450 --atr 28 --atr-mult 2 --cap midcap
# NIFTY futures: lot rounding + margin
python3 scripts/risk.py size --capital 800000 --risk-pct 1 --entry 24950 --stop 24800 --lot-size 65 \
--margin-per-lot 165000 --cost-pct 0.06
# MTF at 3x
python3 scripts/risk.py size --capital 300000 --risk-pct 1 --entry 820 --stop 790 --leverage 3
# Win rate / payoff / Kelly from your journal (date,symbol,side,entry,exit,stop,qty,charges | or pnl)
python3 scripts/risk.py journal trades.csv
```
`--cost-pct` is the round-trip cost as % of entry. Use about 0.25 for delivery, 0.05 for intraday,
and 0.06 for index futures, or compute it exactly with `trading-costs`. Get margin per lot from the
broker's margin calculator or the MCP margin tool, because SPAN changes daily.

How to install
mdr add shubhamkumartrichy/claude-trading-skills-india/position-sizing@sha256:48ecd4bf59131eebThe line at the top of this page pins the label git:20261031.0348258, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
