Why is ROI unavailable when recorded cash risk is zero?
History calculates return on paired cash risk using profit divided by recorded cash risk. If the recorded risk total is zero, the denominator cannot support a percentage, so ROI is unavailable rather than zero or infinite. This is different from missing amount data: a zero may be recorded while other result information is present. The label does not recommend a stake or explain how bonus credit was accounted for.

A zero denominator cannot produce a percentage
Return on cash risk needs a positive cash-risk denominator. When the recorded denominator is zero, History has no basis for expressing the realized result as a percentage of risk.
A known settled outcome or profit amount does not change that denominator. History can retain the result details while marking ROI unavailable.
Zero and missing are different states
Missing risk means the record does not provide the amount needed for the calculation. Zero risk is a recorded numeric value. Both can leave a percentage unavailable, but for different reasons.
Do not replace a zero denominator with a tiny amount to manufacture an infinite return, and do not read unavailable as a 0% ROI. The display preserves the calculation limit instead.
- Recorded zero cash risk makes the percentage undefined.
- Unavailable is not the same as a zero-percent return.
- The label makes no assumption about bonus-credit accounting.
Review result and risk as separate figures
History can show settled-result information independently of the return-on-risk percentage. Review the amounts and data coverage shown for the record instead of treating ROI as a substitute for them.
This explains the displayed calculation state; it is not staking advice or a claim about future performance.
A known result with zero recorded risk
Hypothetically, a settled record has a known realized result but its paired cash-risk total is recorded as zero. History can show the available result and still leave ROI unavailable because the denominator is zero. It does not label the return infinite or assume an amount that was not recorded.
Related questions
Does unavailable ROI mean the return was zero?
No. It means the recorded denominator cannot support a percentage; History does not replace that state with 0%.
Could a positive profit make ROI available with zero cash risk?
No. A known numerator does not make a zero denominator usable for the return calculation.
