how it works
A scheduler, an edge function, and the public web.
No proprietary feeds, no API keys, no server to maintain. Six pieces fitting together cleanly.
-
01
Postgres cron fires
pg_cronruns in the database and triggers on a UTC schedule. Each job is duplicated at both possible UTC times so the system is DST-proof year-round. -
02
Edge function wakes
A Deno/TypeScript function on Supabase Edge runs guards (weekend, holiday, market-state, hour). If anything's off, it exits silently — no stale messages.
-
03
Score past predictions
Looks up every prediction whose horizon has passed, fetches the actual close from Yahoo, and grades it using the direction-plus-meaningful-move rule.
-
04
Generate new forecast
Pulls fresh data for all 16 tickers plus SPY in parallel. Computes a multi-signal lean (momentum, intraday trend, SPY co-move, opening gap), caps it to the realistic intraday range, and assigns a confidence based on signal agreement.
-
05
Log to Postgres
Every signal lands in the predictions table with its entry, target, horizon, and confidence — feeding the next day's track record.

06
Telegram delivery
A single POST to the Bot API. The message arrives in your pocket whether your laptop is open, closed, or in your backpack.

the metric
Honest scoring. No vanity numbers.
Hitting a price target within a dollar isn't realistic on individual stocks. So neilAI measures something better.
right = same direction AND the move was meaningful
"Meaningful" means the actual move covered at least 30% of the predicted move, with a floor of 0.5% of price (so a stock that barely twitched in the right direction doesn't get a free pass).
right
Entry $100 · Target $150 · Close $140
Direction up · move covered 80% of predicted
wrong
Entry $100 · Target $150 · Close $102
Direction up · but only 4% of predicted move
wrong
Entry $100 · Target $150 · Close $90
Wrong direction
built solo
A 16-year-old, a free database, and a Telegram bot.
neilAI started as a frustration with TradingView's free tier and ended as a small piece of infrastructure that runs whether anyone's watching.
