Deriv Even / Odd bots: how the contract works and which bot to run

An Even / Odd contract asks one thing: will the last digit of the final tick be even or odd? There is no barrier to pick and no price target to reach, so every Even / Odd bot comes down to its entry rule, which decides when to trade and which side to buy, and its staking. This guide covers how the contract settles, what changes between markets, and the Even / Odd bots you can run free on BinaryTick.

How Even / Odd settles

Every Deriv price ends in a digit from 0 to 9. An Even / Odd contract reads the last digit of the final tick.

• Even wins on 0, 2, 4, 6 and 8.
• Odd wins on 1, 3, 5, 7 and 9.

Each side wins on five digits out of ten, and 0 counts as even. A win pays a fixed amount: on 12 October 2026 a 1 USD stake returned 1.95 USD, so each win added 0.95 to the balance and each loss cost the 1 USD stake.

That fixed split is the difference from the other digit contracts. On Over / Under you move a barrier to change which digits win and what a win pays. On Even / Odd neither moves, so what sets one bot apart from another is its entry rule and its staking.

Does the index or the tick count matter?

Not for the payout. On 12 October 2026 Deriv quoted 1.95 USD for a 1 USD stake on Even and Odd across Volatility 10, 25, 50, 75 and 100, Volatility 10 (1s) and 100 (1s), and Jump 25, at 1, 5 and 10 ticks alike.

What does change is pace. The standard Volatility indices tick every 2 seconds and the 1s indices every second, so a bot that trades on every tick places twice as many trades on a 1s market. Duration only adds waiting, because the contract still settles on one digit, the last one. Every Even / Odd bot on BinaryTick ships with a one tick contract.

The Even / Odd bots on BinaryTick

BinaryTick has 11 Even / Odd bots, all free, on the Even / Odd page. They fall into a few kinds.

Every trade, one rule. Even / Odd Switcher buys Even until a trade loses, then Odd until that loses, and so on, on Volatility 25. Parity Sprint buys the opposite parity to the digit that just landed, on every tick of Volatility 100 (1s). Its card spells out why: consecutive digits are independent, so the rule exists to keep the bot in the market on every tick.

Bots that count a window of digits. All three run on Volatility 10. Parity Balance counts the evens and odds in the last 20 digits and backs the side that is behind, once it trails by 4. Parity Momentum reads the same count and backs the side that is ahead. Parity Alternation counts something a split cannot show: how often the parity switches from one digit to the next. Frequent switching and it trades the flip; long runs and it trades the run continuing.

Bots that wait for a run. Both run on Volatility 10. Parity Streak Ride waits for three digits of the same parity in a row and buys that parity again. Parity Streak Break waits for five and buys the other side. A run of five takes about 31 ticks to turn up on average, roughly a minute on Volatility 10, so Streak Break sits in the Longer scans group. Lower Streak needed and it trades more often.

A bot that reads the price. Quiet Parity, on Volatility 10, compares how far the price has been moving lately with what is normal for the market. While it is moving hard the bot stays out. Once things go quiet it buys the parity of the newest digit.

Bots with their own staking. Three Even / Odd bots replace martingale with a different progression, so you can compare staking styles on the same contract.

• Fibonacci Recovery, on Volatility 25, steps along the Fibonacci sequence after a loss, so the stake grows by about 1.6 each time instead of 2.1, and steps back two places after a win.
• Paroli Streak, on Volatility 50, does the opposite of a martingale: it doubles after a win, drops back after a loss, and banks the run after three wins in a row.
• D'Alembert Ratchet, on Volatility 25, adds one step to the stake after a loss and removes one after a win. It scans the last 50 digits and trades against the bigger side once evens make up 58% or more of them, or 42% or less. Once the session is 5 USD up, it stops if profit falls 2 USD from its peak.

Every bot explains its rule under How it works on its card, and every number it uses is under Settings, so you can read a bot before you press Run bot.

The settings that matter

Martingale. The eight Even / Odd bots without built-in staking ship with a 2.1x martingale and a max stake of 5 USD. The ladder runs 1, 2.1, then 4.41 USD, and the max stake sends it back to 1 USD after that. Because a win pays close to the stake, a win at 4.41 USD returns 4.19 USD in profit, more than the 3.10 USD lost on the two trades before it, so 2.1x wins back the whole run. Untick Use martingale for a flat stake.

Minimum lead and Streak needed. These decide how often Parity Balance, Parity Momentum and the two streak bots trade. A smaller Minimum lead or a shorter Streak needed means more trades. Raise them and the bot waits for a clearer pattern.

Max losses in a row. Most Even / Odd bots stop after 4 losses in a row by default. Even / Odd Switcher stops after 5, Fibonacci Recovery after 6 and Paroli Streak after 10.

Stop loss and take profit. Both default to 10 USD, so every session ends one way or the other. Set them to amounts that suit your balance before you run. The guide to stop loss and take profit covers how the three limits work together.

Run one now

Open the Even / Odd bots and run one on your demo balance first. Even / Odd Switcher is a good place to start: one rule, one tick, and you will see the martingale ladder climb and reset inside a few minutes. Then try Paroli Streak or Fibonacci Recovery to see how a different progression changes the same contract. Even / Odd vs Over / Under compares the two contracts side by side, and the digit bots guide adds Matches / Differs. For the ladder itself, see how the martingale multiplier works.
