You still fly the plane.
We give you the instruments.

A free weekly letter for self-directed investors. It covers one idea per issue in 5 to 8 minutes: a written process, machine learning with clear limits, and risk rules set before any trade.

Why this letter exists

More information won't fix it. Structure will.

Most investors are either on autopilot with no way to adjust for risk, or chasing headlines with no flight plan. This letter gives you a process instead of another prediction.

🎯

Guessing, not a plan

Trades start from headlines or gut feel, with no written rule for entry, exit or size.

🤖

AI hype

Tools hint that they predict the market, and nobody explains what the model actually does.

📈

Backtests you can't trust

Nice numbers with hidden assumptions and no worst case shown.

⚠️

Fear of a big loss

A new strategy feels risky when you can't see the limits before you start.

What we help you fix

Four answers, one for each problem

A written process

Every decision checks market regime, model evidence and portfolio risk first. The reasoning is logged before you act.

ML with a veto, not a steering wheel

The model scores whether today looks like conditions where a setup worked before. It can block a trade. It can never start one.

Numbers you can audit

Every trade, price and assumption is published, along with the worse result next to the better one.

Risk limits in the code

Size caps, cash reserves and loss cuts are set by rule, not by willpower on a bad morning. See below.

Risk management

"What if this new strategy blows up my account?"

It's the right question to ask. Here's what keeps a single bad trade or a bad month from turning into a disaster. Each rule is applied by the system, not left to discipline.

1/3 max

Per position

No single position can take more than one third of the account.

3 positions

Maximum open at once

Exposure is capped, so the account is never all-in on one idea.

5% + cash

Cash reserve

A minimum reserve always stays in cash, and it grows when volatility rises.

2× credit

Losers cut early

A short option is closed once its loss reaches twice the credit received, so small losses don't become big ones.

7 gates

Before any entry

A trade must clear every gate, including trend, volatility, regime and ML confidence. Eleven entries in 5.5 years: most weeks, nothing needs doing.

↓ auto

Exposure steps down after losses

After a losing stretch, the system takes less risk automatically instead of trying to win it back.

Defined risk on the core position

A long LEAPS call can never lose more than what you paid for it. You know your maximum loss on that position before you enter.

A basket, not a single stock

QQQ holds 100 companies, so there's no single-company blowup, and pricing is tight with easy exits.

Your account stays yours

TradeMind never connects to your broker, places orders or holds your money. You decide and place every order.

Start without options

QQQ Defensive needs no options approval, and the first month is refundable, so you can watch the process before committing.

We publish the number that hurts, not just the one that flatters. These are hypothetical, backtested or simulated results, not live accounts. The next drawdown could be deeper. Options can lose the entire amount invested.

What Machine Learning Can and Cannot Do for Investors

Problem: AI is sold as a crystal ball. You get: where the model helps (ranking and vetoes) and where it never goes (starting trades).
