Digit analysis, every market at once
Read the last-digit distribution of any Deriv volatility index across 30 to 1,000 ticks — or scan every market simultaneously and watch them update live. Free, instant, and no sign-up required.
Three tools, one tab
DCircle — the whole board
Scans every synthetic market at the same time across 30, 60, 100, 120, 240, 500 or 1,000 ticks. Each market gets a card with a ten-digit percentage circle colour-ranked from most to least frequent, the last eleven digits as even/odd tiles, the live price and an Even/Odd bar. Flip on auto-scan and it refreshes every five seconds. Nothing else in the Deriv ecosystem gives you this view.
Signal AI — single-market scanner
Choose a market and a sample of 100, 250 or 500 ticks and hit scan. You get a clean 0–9 frequency histogram plus the Over/Under and Even/Odd splits, with continuous re-scanning if you want it running alongside your trading.
Analysis Tool — deep dive
One market, with an Even/Odd or Over/Under toggle and a configurable barrier digit, so you're looking at the split at exactly the barrier you intend to trade.
What traders use it for
- Choosing a market. Seeing all the volatility indices side by side makes the differences between them obvious in a way a price chart never does.
- Setting barriers. The configurable barrier digit shows you the exact split for the contract you are about to place.
- Testing claims. When someone tries to sell you a bot that "detects digit bias", you can check the premise yourself in thirty seconds. This is the tool's most valuable use, and it will save you money.
- Training your instincts. Watching a "hot digit" appear and dissolve across successive scans is the fastest cure for pattern-hunting there is.
What the numbers mean
Deriv's volatility indices draw each tick's last digit independently and uniformly from 0–9. Across a big enough sample the distribution is flat, and each digit is independent of the one before it — so the frequencies here describe what has happened, not what comes next.
Concretely: across 500 ticks you expect each digit about 50 times, with a standard deviation near 6.7. Anything between roughly 37 and 63 occurrences is unremarkable. A digit showing at 14% looks dramatic and is ordinary noise. Knowing that number is what turns this from a slot machine into an instrument. More on how digit contracts are priced →
On the name. Signal AI contains no AI — no model, no learning, no prediction. It counts last digits and charts them, and the same goes for the Pro AI bots, which are fixed rule-based conditions. The label is a holdover and we'd rather tell you than let it imply something untrue.
Free vs. the paid alternatives
A few sites sell a version of the same idea — last-digit frequency and Even/Odd/Over/Under splits — as a subscription. The underlying math doesn't change based on price; what differs is what's gated and how it's branded.
| Option | Cost | What you get | Worth knowing |
|---|---|---|---|
| Binary Pro This tool |
Free | Every synthetic market at once, live, no account required | Frequencies only — no signals, no predictions |
| DTide | From about $5/month | AI-branded digit predictions | Digits are independent (see above) — the "AI" label doesn't change what any frequency counter can tell you |
| LDP Analyzer / Analyzer Pro | Free tier + paid "Pro" | Last-digit pattern analysis | Compare the free tier's market coverage and history length against the all-market view here |
| Digit Tracker, NexTrader and similar | Free or freemium | Frequency and streak tracking | Worth comparing feature-for-feature — the math behind all of these is identical |
The honest reason this one is free: it's a frequency counter, not a forecasting model, so there's no proprietary "signal" to protect behind a paywall. If any tool — including this one — ever claims to predict the next digit rather than describe the last several thousand, that claim is what deserves the scrutiny, not the price tag.
The rest of the toolkit
- Backtester — thousands of simulations of your staking plan against real contract odds, plus a chi-square test of digit uniformity on 1,000 live ticks.
- Auto Trader — watches live conditions (Over/Under percentage, Rise/Fall percentage, Even/Odd streaks) and alerts you when one triggers, leaving the trade decision to you.
- Day Trader — how long Accumulator runs last at a given barrier: median run, share reaching your tick target, longest observed. See the Accumulators guide.
- DTrader panel — manual trading for Rise/Fall, Even/Odd, Over/Under and Matches/Differs on the same connection the bot engine uses.
