ImprovisingOne month

Decisions made on a whim almost every day: a tip, a headline, a red day.

With a processOne month

A few decisions a month. Each one made when a written rule said it was due. Most days there's nothing to do.

Same market. Same stocks. Fewer, better decisions.

What people tell us before they join

Sound familiar?

"I'm good at buying, but I never sell." "I just round trip stuff." "Holdings wise, I just made it up." "Time is my biggest thing." "I've been putting it off for a long time."

Said on calls with David & Tim.

What actually changes

Money is the score. What you get back is your head.

Before
After
Your evenings
Prices. Takes. Refreshing.
The market runs without you watching it.
Your wins
"Skill or luck?"
You know why it worked. You can do it again.
Your losses
Proof you don't belong here.
The exit rule fired. You sold. That's it.
Your head
At the mercy of the market.
You don't control the market. You control what you do.

Calm between decisions. Decisive when one is due.

Members

In their own words.

"No more gluing myself to the screen or obsessing over daily market movements. Greater profitability with far less stress."

Elena Tanevska, member

"Now I don't feel wedded to any single stock. I feel like the system has given me permission to get out of bad relationships with stocks that don't pay haha"

Kez Singh, member

"I felt like I have bought the rod that I will be fishing with for years to come."

Trader Edwin, public post on X, May 2026

"I have grown from no knowledge to understanding stocks and shares… not to mention the daily support of Tim in the Discord as well as the other members."

Karen Westgate, public post on X, May 2026

"FINK is like a surf instructor who gets in the water only when conditions are right and teaches you to identify a wave and how to time your ride."

Before you decide

Questions people ask.

How much time does it take each week?

Most people complete the course in a week or two. After that, most days there's nothing to do. You act only when one of your rules says so.

I'm new to investing. Is this too advanced?

No. If anything, starting from scratch helps. You've got no bad habits to unlearn. We start with the basics (what owning a share actually means, why prices move) and build up one layer at a time: Filter, Enter, Size, Manage, Exit. Get stuck? Ask in the community.

I already have a portfolio. Do I have to start again?

No, you don't start again. We apply the five rules to what you've already got, so everything in there gets the same questions: why it's there, how big it should be and what gets you out. It's process, never advice: we won't tell you what to keep or what to drop. You make the call.

Is this day trading?

No. We're completely against day trading. We look at trends that might last from three months to a year. Most of the time there's nothing to do.

Do you give stock tips?

No. We're never going to tell you what to do. If we did, you'd never own the decision. We teach the process so you can make it yourself.

Can I pay in dollars or euros?

Yes. Switch the currency above the price and you'll see the amount in pounds, dollars or euros.
