CHAPTER 7 · MINDING THE POSITION

Maman Brigitte

Most tools help you buy and then leave you alone. Brigitte is the opposite — she is the desk that minds a position after you open it: your portfolio, a watch on the reason you bought, calm exit rules, and a four-gate ritual for the moment you want to panic-sell.

7.1Portfolio & DCA

Brigitte is the room you visit after you have coins. She holds a portfolio tracker, a thesis-watch called the Vigil, exit tools, a loss-interceptor called the Passage, and a small swap quote — the whole after-the-buy life of a trade in one place.

THE BRIGITTE DESK IS MEMBERS-ONLYThe full Brigitte desk — the portfolio & DCA tracker, the Vigil thesis-watch, the exit tooling, and the Passage — is a Members-only (paid) feature. If you want a portfolio and DCA tracker with no account required, use the Portfolio Manager at /portfolio (Chapter 8) — it's free and runs entirely on your own device.
EVERYTHING STAYS ON YOUR DEVICEEvery holding, thesis, and journal note in Brigitte is saved in your browser's own local storage — a private drawer on this computer or phone. It is never sent to a server, never seen by us, and never shared. The trade-off: it lives on one device. Clearing your browser data, or switching phones, empties the drawer.

Add a holding

A holding is simply one coin you own, and how much of it. Adding one takes four small steps.

  1. Search the coin. Type a name or ticker (like ETH) in the search box, or paste a token's contract address — the long string that is the coin's unique on-chain ID — and pick it from the list.
  2. Enter the amount. Type how many units you hold — e.g. 0.5 ETH, not dollars.
  3. Add your cost basis (optional). Your cost basis is what you actually paid per unit. Fill it in and Brigitte can show real profit/loss; leave it blank and she just tracks the live price.
  4. Click "Add to portfolio." The coin drops into your holdings table and starts updating with live prices right away.

  4. Concentration warning — a red flag when any one coin is more than ~40% of your total. Concentration means too many eggs in one basket.
  5. Refresh — pull fresh live prices for every holding at once.
BUY MORE / SELL SOME DO THE MATHWhen you tap + buy more at a new price, Brigitte updates your average cost basis automatically — you don't calculate anything. − sell some reduces the amount and keeps your books straight.

The DCA calculator

DCA stands for dollar-cost averaging — buying a fixed amount on a regular schedule (say, $50 every week) instead of betting one lump sum on a single day. It smooths out the price you pay over time. The calculator lets you play out a plan before committing a cent.

  1. Enter a starting amount. What you'd put in on day one (it can be $0 if you're starting from scratch).
  2. Enter a weekly contribution. The fixed amount you'd add each week.
  3. Enter a number of weeks. How long you'd keep it up.
  4. Enter today's price and click "Run." Brigitte shows total invested, what it's worth today, your profit, and your average cost per unit.
FieldWhat it means
Starting amountYour first, upfront investment.
Weekly contributionThe fixed sum you add every week — the heart of DCA.
Number of weeksHow many weekly buys the plan runs for.

7.2The Vigil — a watch on your reason

Here is Brigitte's core idea. When you open a position, you write down why you bought — that "why" is your thesis. The Vigil then watches whether that reason still holds, and warns you the moment it breaks.

Most people watch price. But price is the last thing to move. Your real reason for buying — a rising narrative, healthy on-chain behaviour, a clean chart structure — usually cracks first. When your thesis stops being true, it is invalidated. Invalidation is the honest line where you'd have to admit "I was wrong," and the Vigil is built to spot it earlier than price alone ever would.

Record a thesis

  1. Search the coin you want to watch.
  2. Set the direction. Long means you profit if it rises; short if it falls.
  3. Fill in the thesis form. Entry price, a plain-words statement of your reason, and — most important — an invalidation level: the price or condition that would prove you wrong.
  4. Add the optional pieces (all explained in the table below), then click Record thesis. It appears as a card with a live verdict and your running P&L.

  1. Live verdict — the Vigil's read: checking (still gathering), intact (reason holds), review (something's off — look), act (your invalidation is hit).
  2. Thesis statement — your reason, in your own plain words. The whole point is that you named it out loud.
  3. Invalidation — the line that proves you wrong. When it's crossed, the verdict turns to act.
  4. Target & exit settings — where you'd take profit, plus the trailing-stop and take-profit-ladder rules (see 7.3).
  5. Watch checkbox — paid accounts can opt in to be emailed once if the thesis dies while they're away.

Every field, in plain words

FieldWhat it does
DirectionLong = you win if it rises; short = you win if it falls.
Entry priceThe price you got in at — the anchor for P&L and every level below.
Thesis statementYour reason, in a sentence. "AI narrative heating + clean breakout."
Invalidation levelThe price or condition that proves you wrong. The single most important box.
Target (optional)The price where your idea has "worked" — your finish line.
Dead-money clockA time limit. If it hasn't moved by then, the money is "dead" and could work harder elsewhere.
Trailing-stop %A stop that ratchets up as price rises (see 7.3).
Take-profit ladderLevels to scale out at, e.g. 30:25,60:50 = sell 25% at +30%, 50% at +60% (see 7.3).
Heat thresholdThe narrative-heat level below which your "story" has cooled off.
Regime lineTies the thesis to the market's weather — e.g. "only while RISK-ON."
AccountWhat you get
Unlimited theses plus the opt-in email watch — tick the box and Brigitte emails you once if a thesis is invalidated while you're away.
Maman Brigitte says"I do not watch your price. Anyone can watch a price. I watch the reason you gave me — and I will tell you when it has left, even if the number hasn't caught up yet."

7.3Exit tooling — decide while you're calm

The hardest moment to think clearly is when money is moving. So Brigitte lets you set two disciplined exits ahead of time, while you're calm, so they're ready when you're not.

The trailing stop

A trailing stop is a sell line that ratchets upward as the price rises but never falls back down. Set it at, say, 12%: if the coin climbs, your stop climbs with it, always trailing 12% below the highest point — locking in gains. If the coin then drops 12% from its peak, the stop is your exit. It protects profit without you staring at the screen.

The take-profit ladder

A take-profit ladder means scaling out in steps at pre-set gains instead of trying to nail one perfect top. You write it as gain:percent pairs. For example 30:25,60:50 reads as: take 25% off the table at +30%, and 50% off at +60%. You bank profit on the way up and still keep a piece running.

SET THEM ONCE, TRUST THEM LATERBoth tools attach to a Vigil thesis. Decide the numbers now, while nothing is happening — then the plan carries you through the moment emotion would have made the call for you.

7.4The Passage — four gates before you panic

Some positions go under water. Your finger hovers over the sell button, your heart is loud. The Passage is a short ritual that walks you through four gates before anything happens — not to stop you, but to make sure the decision is yours and not your fear's.

⚜ THE PASSAGE · FOUR GATES ENTER THE PASSAGE STOP take a breath click to continue ✋ SEE pick the position entry · mark · P&L −18% NAME reason still holds reason is gone I don't really know CROSS cooldown: 0 · 1h · 4h 24h · 3 days RECORD THIS CROSSING › › › 1 2 3 4
The Passage — Stop, See, Name, Cross
  1. Gate 1 · Stop — take a breath and click once to continue. Nothing else. The pause is the point.
  2. Gate 2 · See — pick which position turned; it lays out the honest facts: your entry, the current mark, and your unrealized loss.
  3. Gate 3 · Name — say it plainly: "my reason still holds," "my reason is gone," or "I don't really know."
  4. Gate 4 · Cross — set a cooldown (no hold · 1h · 4h · 24h · 3 days), optionally journal a note, then record the crossing.
  1. Click "Enter the Passage." You leave the noise of the chart and step into the ritual.
  2. Gate 1 — Stop. Take one real breath. Click to continue. That's the whole gate: a deliberate pause before your hand moves.
  3. Gate 2 — See. Choose the position that turned. Brigitte shows the honest numbers — entry, current mark, unrealized P&L — no spin, no hope.
  4. Gate 3 — Name. Pick one: my reason still holds, my reason is gone, or I don't really know. Naming it out loud separates the trade from the fear.
  5. Gate 4 — Cross. Set a cooldown — none, 1h, 4h, 24h, or 3 days — write an optional note to your future self, and click Record this crossing.
THE PASSAGE NEVER TELLS YOU WHAT TO DOIt gives no advice, places no order, and moves no money. It runs entirely on your device and journals privately to your own log. Its only job is to make sure you decided — clear-headed — instead of your panic deciding for you.

7.5Swap quote

A small panel for a quick "what would I roughly get?" check — with the real swap widget right beside it for when you're ready to act.

  1. Enter a from-coin — the coin you'd give up.
  2. Enter a to-coin — the coin you'd receive.
  3. Enter an amount and click "Quote." Brigitte shows a rough estimate based on the current spot price.
A QUOTE IS AN ESTIMATE, NOT A PRICEThe quote uses spot price only — it excludes network fees, DEX fees, and slippage, so the real result will differ a little. To actually make the trade, use the embedded Uniswap widget right there in Brigitte — the full walkthrough is in Chapter 6 · Swapping in Your Wallet.

7.6The Loop — why all of this fits together

Brigitte isn't a pile of features. She's the back half of one clean loop that runs the whole life of a trade.

THE LOOPGede checks the reason before you enter → the Vigil watches that reason during the trade → the exit ladder or the Passage closes it with discipline. Reason in, reason watched, reason honoured on the way out. That loop — not any single button — is the product.

Learn Gede in the conscience chapter; you've now learned the two steps that come after. The next chapter zooms into the portfolio side in more depth.
