In this section, you can set up several parameters regarding Live Odds, such as the odds rounding and harmonization rules, the dynamic key option, and others that are specific to each sport.

**Odds harmonization across related selections:**&#x20;

Although Betradar calculates the same probabilities for the same events in different markets (e.g. "correct score 0:0", "under 0.5 goals" and "next goal: none") this might result in slightly different odds for these events due to the way the key is applied.&#x20;

If desired you can still force to have the same odds for these events choosing between the options to harmonize via downgrading, upgrading or taking the average of the odds. Please understand that forcing same odds for same events will overwrite your desired key and might result in slight inconsistency within a betting market.

{% hint style="info" %}
**Example:**\
\&#xNAN;*Next goal probabilities: home: 0.40; none: 0.40; away: 0.20; desired key 115*\
\&#xNAN;*Total 0.5 probabilities: over: 0.60; under: 0.40; desired key 108*

In this case, it would be possible to choose from the following options:<br>

* **Accept differences in odds:** Same events might have slightly different odds in different markets home: 2.200; none: 2.200; away: 4.190; key=115

over: 1.56 under: 2.270; key=108<br>

* **Force same lowest: T**he lowest odds from the same events will be kept and applied across both markets

home: 2.200; none: 2.200; away: 4.190; key=115

over: 1.56 under: 2.200; key=109.5<br>

* **Force same average:** The average odds from the same events will be calculated and applied across both markets

home: 2.200; none: 2.235; away: 4.190; key=114.1

over: 1.56 under: 2.235; key=108.8<br>

* **Force same highest:** The highest odds from the same events will be kept and applied across both markets

home: 2.200; none: 2.270; away: 4.190; key=113.4

over: 1.56 under: 2.270; key=108

* **2 digits:** Odds will be sent with 2 decimal places. Each price will be rounded independently (e.g. 1.01, 1.02, ..., 99.99, ...)

&#x20;

* **5 digits:** Odds will be sent with 5 decimal places. Each price will be rounded independently (e.g. 1.00001, 1.00255, ..., 99.12345, ...)

**Action on Minimum offer:** when the min offer value is reached, it is possible to select whether the specific outcome with low odds is deactivated (deactivate odds field) or the whole market is suspended (deactivate odds type)

**Dynamic key on active selections:** if enabled, this option adjusts the margin as the number of market outcomes decreases.

Markets with more outcomes tend to have a higher key. During live trading, some outcomes might become impossible. You can set this configuration to let the desired key decline dynamically in these cases to stay competitive with your odds. The key declines linearly towards 1.10 for the two remaining outcomes. This functionality will never increase your key, though. The exact formula applied here is as follows:

key\_new = desiredKey - (desiredKey -1.1) / (#outcomesPre - 2) \* (#outcomesPre - #outcomesIngame)

{% hint style="info" %}
***Example:***

\
\&#xNAN;*Tennis - Final Result (in sets - best of 5); Number of outcomes: 6; Desired key: 1.20*\
\&#xNAN;*Current score: 6:3, 4:6, 2:6, 2:1*

*Since only the outcomes "3:2", "2:3", "1:3" remain, your odds are adjusted towards the key 1.125 instead of the original key 1.2.*
