Digit Frequency Scanner
Builds a rolling histogram of recent digits and fades whichever side is over-represented.

- Volatility 100 Index
- Pace
- Longer scans. The slowest bot here. It only acts when a run of digits is genuinely lopsided, so on a two-second market it can sit out for several minutes. Shrink the sample size, or move the two bias thresholds closer to 50, to trade more often.
How it works
- On every tick it walks the last N digits and counts how many fell below the barrier, then turns that into a percentage.
- If low digits are over-represented above the upper bias, it buys Over the barrier.
- If low digits are under-represented below the lower bias, it buys Under the barrier.
- After a loss it stops trading for the cooldown period and multiplies the next stake.
- It stops entirely on take profit, stop loss or the consecutive-loss limit.
- Rolling digit histogram
- Deviation threshold
- Loss cooldown
- Martingale with cap
Staking
It ships with a 1.9x martingale, sized to win back a losing run of up to 3 trades inside its stop loss, with a max stake of 4. Untick Use martingale on its card to stake the same amount on every trade.

| Sample sizeHow many recent digits the histogram covers. | 50 | 10–200 |
| Lower bias (%)Buys Under when the share of low digits drops below this. | 35 | 1–49 |
| Upper bias (%)Buys Over when the share of low digits climbs above this. | 65 | 51–99 |
