Trade the trend.
Follow the rules.
Most traders don't lose because they lack predictions — they lose because rules are hard to follow when money is moving. Trendkept turns your written trend-following rules into software: sized by risk, stop-loss sent with every entry, scored honestly in R-multiples.
Free forever · one email a Sunday · check your inbox to confirm · unsubscribe anytime.
The free toolkit is for traders comfortable with a terminal (Python + GitHub — get it here). Pro, coming soon, is one-click for everyone else — the weekly email is where we'll announce it.
Most days, the answer is “do nothing.” That's the discipline part. The board from Saturday 29 August 2026 — what the rules said, ticker by ticker. Descriptions of data, not advice.
Watch it decline a trade
The scan, the dashboard, an honest backtest, and the real paper account — losses included. No voiceover, no music, nothing staged.
Served from this site — no third-party player, no cookies, nothing loaded from anyone else.
Three parts. One loop.
The software carries the hard part.
Write your rules once
Describe how you trade in plain English — “My Trading Diagram.” Averages, entries, risk per trade. Every scan, chart and backtest runs your ruleset, not ours.
The engine enforces them
Daily scans say exactly what the rules say — including “do nothing,” the most common right answer. Entries go to your broker with the stop-loss attached in the same order.
The journal keeps you honest
Every completed trade is scored in R-multiples straight from your broker's records — profit measured against planned risk. You can't fool a journal that fills itself in.
Not another journal.
Not another broker order.
Trading journals
Edgewonk, TraderSync, Tradervue — good tools that score your discipline after the fact. By the time the journal sees the trade, the damage is already sized, entered and un-stopped.
Broker bracket orders
A bracket enforces one static stop on a trade you already chose. It won't tell you whether the trend qualifies, size the position off your risk, or trail the stop as the structure moves.
Trendkept — the layer between
It structures the trade before it exists — trend qualification, risk-based sizing, stop attached to the entry — then trails the stop daily and scores adherence after. One ruleset, enforced end to end.
The five rules
Free forever — the whole point is following them.
Trade only a confirmed uptrend. Price above the 50- and 200-day averages, averages aligned, higher highs and lows. Otherwise: stay out. No exceptions.
Enter without chasing. A pullback that resumes, or a breakout — never a move that's already run far.
The stop goes in with the order. Just below the last swing low, enforced by your broker — decided before the trade, not during the drawdown.
Size by risk, not by gut. If the stop is hit, lose no more than 1–2% of the account. The formula has no conviction knob.
Let winners run; cut the break. Trail the stop up under each higher low. Exit completely when the trend breaks.
The honest part. You can be wrong more than half the time and still come out ahead — because each loss is capped small and winners run. That only works if you follow the rules every time. That's the hard part. That's what Trendkept is for.
Calculators — no sign-up, no catch
The maths behind the rules, as four little tools you can use right now. They're a taste of what Trendkept automates on every trade.
Position size calculator
How many shares to buy so a loss costs no more than you decided. The flagship.
Open → 02Risk per trade calculator
What 0.5%, 1% or 2% of your account is per trade — the 1% rule, in pounds.
Open → 03R-multiple calculator
Score a trade in R — profit measured in units of what you risked.
Open → 04Stop-loss calculator
How far your stop sits and exactly how much money is on the line.
Open →Proof, not promises
Two kinds of evidence, both public: backtests that refuse to cheat, and the rules trading a real paper account in the open — wins, losses and boring days on the record.
Backtests that can't peek — this is the report, not a pitch.
We show you this to demonstrate what an honest backtest refuses to do: it can't peek at the future (a signal at bar i uses only data up to bar i), it puts the drawdown on the same line as the return, and it labels its own fills as idealized. Backtests that peek look brilliant and trade terribly. Run it yourself on any symbol — the number that comes out is yours, not our marketing.
$ python -m trendkept.cli backtest --symbol AAPL --account 1000 --risk 0.02 Starting equity : 1,000.00 Ending equity : 1,252.00 <- one bundled sample, not a promise Max drawdown : -2.28% <- shown as prominently as the gain Expectancy : +7.13R/trade <- idealized fills; reality slips
Past and backtested performance do not predict future results — which is why the strategy reacts to trends instead of predicting them.
Built in public — the log so far.
Free core. Pro when it's earned.
The toolkit is free forever. Pro arrives only after our public validation period — we'd rather earn the right to charge.

Asked and answered — honestly
Does Trendkept predict which way a market will go?
No — and we'd be suspicious of anyone who says they can. Trendkept reacts: it identifies confirmed trends, defines entries and stop-losses in advance, caps every loss by position sizing, and lets winners run. The edge is behaviour, not prophecy.
Do I need a broker account to use it?
No. Scanning, charts, backtesting and the watchlist work out of the box with free public data. If you want it to place paper trades and fill in the journal automatically, connect a free Alpaca paper account (10 minutes, no deposit) — your API keys stay on your machine.
Is my money or data ever in Trendkept's hands?
Never. The software runs on your computer; broker keys never leave it; we can't touch your account and don't want to. Trendkept is analysis and education software, not a broker and not an advisor.
What does it cost?
The core toolkit is free and open source, forever. Pro (the effortless version — one-click install, licensed data, journal insights) will be £12/month when it launches, and the waiting list gets the founding price of £79/year, locked for life.
How is this different from Edgewonk, TraderSync or Tradervue?
Those are journals — genuinely useful, and they prove people pay for discipline. But a journal can only score a trade after it happened. Trendkept works before and during as well: it qualifies the trend, sizes the position off your risk, sends the stop-loss with the entry, trails it daily — and then journals the result. If a journal is a mirror, Trendkept is a seatbelt that also keeps the mirror.
It's open source — can't someone just run it free and never pay?
Yes, and we hope they do — that's the point of the free core. Pro is for people who'd rather not maintain software: one-click install and updates, licensed clean data, insights, support. You pay for the effortless version, not for secrets. (Every serious open-core company works this way.)
Will following these rules make me money?
Honestly: nobody can promise that, and we won't. What the rules do is cap what any single mistake can cost and keep you out of most bad trades. Our backtests are public and refuse to peek at the future; our paper account trades in the open, losses included. Read both and judge for yourself.
