Risk & Position SizingFREE

Stress-test your position-sizing rules before the market does

You have sizing 'rules' you mostly follow. Find out where they break — in a conversation, not in a drawdown.

Act as a risk-management TEACHER (not an advisor — this is educational analysis of my own process, not investment advice; do not recommend any specific security, position, or trade). I will describe my position-sizing rules and account context in general terms. Your job:

A) RESTATE my sizing rules as explicit IF/THEN logic, flagging anything vague ('I size down when unsure') that isn't actually a rule.

B) STRESS SCENARIOS — walk my rules through: 3 losing trades in a row; a position gapping through my planned exit; correlated positions moving together; volatility doubling. For each, show what my rules would have me do and where they're silent.

C) THE HOLES — the top 3 situations my rules don't cover, phrased as questions I need to answer for myself (do NOT answer them with recommendations).

D) TEACH — explain the general principle each hole relates to (risk-of-ruin, correlation risk, gap risk) in plain language with a generic numeric illustration.

My sizing rules & context: [DESCRIBE — e.g. 'I risk a fixed % per trade, max N open positions, no rule for correlated names']

Rules: Never tell me what to buy, sell, or how large any real position should be. If I ask for a pick or a target, refuse and return to process. This is education about MY rules, not advice.

Use AI today — a workflow to steal

WorkflowFREE

Turn any meeting recording into decisions + owners

The follow-up email is where most of a meeting's value leaks away. This produces it in 30 seconds and makes you the person who always sends the recap.

Record the meeting (Zoom/Teams/phone memo), get the transcript, and paste it with: 'Extract every DECISION, every ACTION with an owner and due date, and every OPEN QUESTION. Table format.'
  1. Grab the transcript (most tools export one).
  2. Run the extract prompt.
  3. Skim, fix names, send as the recap.

Sharpen it: Treat it as a conversation, not a vending machine. The magic is in the second, third, and fourth message — 'more specific,' 'shorter,' 'now for executives' — not the first.

Better together
Make prompts remember you: Brainfile

Even a sharp prompt starts from zero unless your AI knows you. Brainfile is persistent context — your work, voice, and priorities loaded into every session. Brainfile is the memory; PromptSharp is the playbook. Together they compound — the same prompt gets sharper because it runs on YOUR context.

PromptSharp prompts are drafted with AI assistance and human-reviewed. They structure how a model reasons over data you provide — they do not source or verify facts for you, and you own every output. Nothing here is financial, legal, tax, or investment advice. Never paste confidential, client, or material non-public information into consumer AI tools; follow your employer's AI-use policy. © 2026 PromptSharp.
