We always do our due diligence.
Welcome in! Due Diligence is a small research studio with a big curiosity about the stock market. We test trading ideas on sixteen years of real prices, keep the good ones, and happily tell you about the ones that tripped over their own shoelaces.
Whether you've traded for years or just got curious this morning, there's a seat for you here.
How our headliner works, drawn out: wait for the overnight dip to yesterday's low, aim for a small bounce, and keep a safety stop far below. An illustration, not real prices.
Every great trip starts with a few local words. Here are the six you'll hear most around here, so nothing on the tour sounds like a secret code.
Futures
A contract that rides along with a whole market. NQ follows the Nasdaq-100 (home of the big tech names) and ES follows the S&P 500. They're night owls: they trade almost around the clock.
Micro contract
The fun-size version of a futures contract (MNQ, MES): one tenth the size, so every win and every oops is one tenth too. Our results are shown per micro.
Indicator
A helper that draws on a price chart. Ours mark the prices that matter and leave friendly notes like "armed", "stay away" or why today's a rest day. They never trade for you.
Backtest
A time machine for ideas: we replay a rule on years of past prices to see how it would have done. Wonderful for learning, though the future always writes its own story.
Target and stop
The two exits you pick before the ride starts. The target is where you collect the prize; the stop is the safety bar that ends a trade that isn't working.
Options on QQQ and SPY
QQQ and SPY are funds that track those same two markets. Options are contracts on them; a call gains when the price climbs. Some of our alerts point to one worth a look.

Our research, drawn right on your chart.
Think of them as a friendly co-pilot. They mark the prices that matter, let you know when an idea is ready, and politely suggest sitting one out when the conditions aren't right. You're always the one at the wheel.
Works with TradingView and NinjaTrader 8, two popular charting apps.

Overnight Dip Buy
While most of the world is asleep, markets often wander back down to the previous day's low and then bounce. This tool keeps watch: it marks that low, waits for price to arrive, and plans a small, tidy profit, with a planned exit in case the bounce doesn't show up.
It even takes the night off after a sleepy day, and its "mood light" reads QUIET, NORMAL or ACTIVE before the evening begins.
01Find yesterday's daytime high and low (9:30am to 4pm, New York time).
02Play only if tonight starts inside that range, after a day that moved more than usual.
03Buy at yesterday's low, aim for a small bounce, and be home by 8:25am.

Morning Breakout
Watches the first hour of the trading day. On cheerful days, a jump above that hour's high is its cue. It's the trusty sidekick rather than the hero: it lost money from 2010 to 2021, and its label says so.

The QQQ/SPY translator
Speaks both languages: it turns futures prices into the matching fund prices (QQQ for the Nasdaq, SPY for the S&P), so you can follow along in whichever market feels like home.

Options Alerts & London Dip
A friendly ping when the morning idea fires on QQQ or SPY, with an example option to explore, plus a London-hours cousin of the dip. Both wear their test results proudly on the label, the good and the not-so-good.

Sixteen years of homework, with every grade on the fridge.
Every idea takes the same exam: real minute-by-minute prices from 2010 to 2026, fees included, and years it had never seen before. Here's how the class did.
The headliner's report card
The Overnight Dip Buy made money in all six of its tests: three stretches of time on two markets, including years nobody peeked at while designing it.
How to read it: "80 · 88%" means 80 trades, and 88% of them made money. Profit is per micro contract, after a $1.50 fee per trade.

A backtest, not real trading. The past is a great teacher but makes no promises about the future.
~2× per trade
One small rule, take the night off after a sleepy day, roughly doubled the average profit per trade while trading less than half as often. Rest really does help.
199 rescue tries
Three other ideas lost money before 2021. We tried 199 filters and 104 tweaks to save them. None of them worked, so we print that right on the chart.
+$18,510
Every signal from Oct 2025 to Oct 2026, simulated on 4 micros per market. It wasn't a smooth ride: it dipped as much as $3,108 along the way, and four months ended in the red.
The market's mood light
Wouldn't it be lovely to know ahead of time when an idea tends to shine? We tested eight warning signs, and one kept its promise for the dip idea: how much the market has been moving lately.
On quiet days the idea about broke even; on busy days it did its best work. Think of it as a weather report, not a fortune teller.

Every chart has a story. We're filming them.
Due Diligence is run by a filmmaker, so the research is headed for the screen: short, well-told videos that make a chart idea click in a couple of minutes.
One idea per episode, start to finish, with the chart right there on screen.

BEHIND THE SCENES
How we test
A peek inside the workshop: how an idea gets tested, graded and sometimes retired.
FIRST STEPS
Getting started
Setting up a chart, adding a tool and practicing on a paper account, step by step.
Our promise, in three parts
Real prices only
Minute-by-minute futures prices straight from the exchange (CME), 2010 to 2026, double-checked against a second source. No pretend data.
Fees always counted
Every result has trading fees taken out: $1.50 per trade on a micro, $4.50 on a full-size contract. We pack the costs before we leave on the trip.
Built with care
Research by duediligence.fyi. Claude, an AI model by Anthropic, helped with research and coding; every result was tested on the real prices above.
About
Research first. Then everything else.
Due Diligence does four things: tools you can put on a chart, studies that put those tools through sixteen years of data, commentary on what the market is up to, and videos that bring it all to life. The promise behind every piece is in the name: do the homework first, and share the whole report card.
