How it works
- An Over contract does not care how high a digit is, only which side of the barrier it lands on.
- So the bot counts what share of the recent digits came in above the barrier.
- It works out the share that should land there from the barrier itself.
- With the barrier at four that is half the digits; a higher barrier leaves fewer.
- It buys whichever side has been arriving more often than it should, once the gap is wide enough.
- Share above the barrier
- Fair share worked out from the barrier
- Counts rather than averages
- Loss cooldown
- Martingale with cap
Staking
It ships with a 2.1x martingale, sized to win back a losing run of up to 3 trades inside its stop loss, with a max stake of 5. Untick Use martingale on its card to stake the same amount on every trade.

Contract
| Setting | Default | Range |
|---|---|---|
| Duration (ticks)Digit contracts settle on the last tick, so one is the usual choice. | 1 | 1–10 |
| Barrier digitOver wins above this digit and Under below it. Further out pays more and wins less. | 4 | 0–9 |
Entry rules
| Setting | Default | Range |
|---|---|---|
| Measuring windowHow many recent digits the share is counted over. | 40 | 5–300 |
| Edge neededHow far past its fair share a side must run before it is backed. | 0.12 | 0.01–0.5 |
| Cooldown after a loss (ticks)The bot sits out this many ticks after a losing trade before it looks for a new entry. | 1 | 0–50 |
Stake progression
| Setting | Default | Range |
|---|---|---|
| Initial stakeThe amount staked on the first trade of each sequence. | 1 | 0.35–1,000 |
| Martingale multiplier1 keeps the stake flat. Above 1 multiplies the stake after each loss. | 2.1 | 1–5 |
| Max stakeIf the progression pushes the stake past this, it resets to the initial stake. | 5 | 0.35–5,000 |
Session limits
| Setting | Default | Range |
|---|---|---|
| Take profitStops the bot once session profit reaches this. | 10 | 1–100,000 |
