Introducing 20TradesStop — the set-and-forget mode we'd actually pick ourselves

Every trading bot ever built shares the same dirty secret: the longer it runs, the more chances it has to hurt you. Most of our users' worst days didn't come from one bad call — they came from a bot that kept trading, and trading, and trading, recycling the same bankroll through dozens of fast-resolving markets until there was nothing left to recycle. So we built the opposite of that. Meet 20TradesStop: pick your 20 best bets, place them, and walk away.

This is not a tweak. It's a fundamentally different philosophy of how an automated weather trader should behave — and honestly, it's the mode we'd recommend to a friend.

What it actually is, in one breath

20TradesStop does exactly three things, and nothing else:

That's the whole product. Its power is in what it refuses to do.

How the AI picks the 20

20TradesStop is picky on purpose. It does not buy the first 20 things it sees — it runs the full Balanced selection pipeline on every candidate and only the highest-quality setups make the cut. Here is exactly what each of the 20 has to survive:

• Four independent forecasts. For every weather market, WeatherBot pulls GFS, ECMWF, UKMO and NWS — four models built by four different institutions on different physics — and blends them into an ECMWF-weighted consensus with outlier detection.
• A real mathematical edge. The consensus is turned into a true probability using a Normal-CDF over the forecast-error distribution, then compared against the market's implied price. If our probability isn't meaningfully different from the crowd's, there is no edge and it's skipped.
• Claude is the gatekeeper. Every surviving candidate is handed to Claude, operating as a senior meteorologist: it examines each model's known biases, the synoptic pattern, microclimate effects, and the market price — and it can veto. Nothing is bought without an explicit AI “BUY”.
• A disciplined price band. Entries are restricted to the 22¢–84¢ range — avoiding both near-resolved longshots and overpriced favorites where there's no value left.
• One position per city, per day. It will not stack four temperature brackets on the same Seoul afternoon. Each of the 20 is a distinct, independent bet.
• Kelly-capped sizing. Each position is sized conservatively (Kelly-capped at 5% of bankroll, never more than 15% of the remaining balance) — so your total exposure across all 20 is bounded and known before the first trade fills.

The result is not a pile of impulse bets. It's a curated 20-position portfolio where every single entry independently passed a four-model forecast, a quantitative edge test, and a senior-meteorologist AI review.

Why “held to resolution” is the whole point

This is the part that matters most, so we'll be blunt about it. In our own data, the single biggest source of avoidable losses was never the entries — it was the exit behavior: a loose trailing stop clipping winners down to break-even, and capital churning out of one market and straight into the next. The math of a prediction market is brutal on a bot that trades constantly.

20TradesStop removes the exit engine from the equation entirely. Once a position is open:

• It is never sold early. No trailing stop to give back your gains. No panic stop-loss on noise. The position rides to the market's actual settlement.
• The outcome is decided by reality, not by price wobble. A temperature market resolves on what the thermometer actually did — which is exactly the thing our four-model forecast is built to predict. Holding to resolution means you're paid for being right, not for being lucky on intraday volatility.
• There is zero churn. Your bankroll is deployed once, into 20 vetted bets, and then it works for you while you do literally nothing.

Why we think this is the best mode for you — and for almost anyone

Put simply: the other modes ask you to trust the bot to know when to stop. 20TradesStop doesn't ask — it has a hard, persistent, mathematically-bounded ceiling baked in. For most people, most of the time, that discipline is worth more than any clever exit logic.

How to run it

• Open the app, find the mode toggle on the Claude AI analysis card, and select 20-Stop (you'll see a live X/20 counter on the button as it fills).
• Start the bot. It will work through high-quality setups, open up to 20, and auto-stop itself.
• Then wait. The positions resolve on their own market dates. There is nothing else to do.
• Want another round? Re-select the mode — that arms a fresh count of 20. A plain restart mid-run does not reset it; it just resumes toward 20.

The honest part

We won't insult you with promises. 20TradesStop is still real money on real prediction markets. Holding to resolution cuts both ways: a position that goes against you is held to a full loss rather than scratched early — that's the trade-off for never giving back a winner. The strategy's job is to make sure the 20 you hold are well-chosen and well-sized so the portfolio math works in your favor over a basket; it is not a guarantee on any single bet. Trade with capital you can afford to commit, and let the sizing do its job. What 20TradesStop guarantees is discipline: bounded exposure, no churn, no over-trading, and a bot that knows when to stop — because we taught it to.
