Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (f)(2)(ii) -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5070-113901 false0Expected common stock price volatility7false 5dcbf_ShareBasedCompensationArrangementByShareBasedPaymentAwardAwardVestingPercentagedcbf_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1falsetruefalse00falsefalsefalse2falsetruefalse00falsefalsefalse3truetruefalse0.20.2falsefalsefalsenum:percentItemTypepureShare based compensation arrangement by share based payment award, award vesting percentage.No definition available.false0Employee share option plan granted8false 5dcbf_ShareBasedCompensationArrangementByShareBasedPaymentAwardExpirationTermdcbf_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1falsefalsefalse00falsefalsefalse2falsefalsefalse00falsefalsefalse3falsefalsefalse0010 yearsfalsefalsefalsexbrli:durationItemTypenaShare based compensation arrangement by share based payment award expiration term.No definition available.false0Expiry term of option9false 5us-gaap_ShareBasedCompensationArrangementByShareBasedPaymentAwardFairValueAssumptionsExpectedDividendRateus-gaap_truenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1falsetruefalse00falsefalsefalse2falsetruefalse00falsefalsefalse3truetruefalse00falsefalsefalsenum:percentItemTypepureThe estimated dividend rate (a percentage of the share price) to be paid (expected dividends) to holders of the underlying shares over the option's term.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (f)(2)(iii) -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5070-113901 false0Expected dividend yield10false 5us-gaap_SharebasedCompensationArrangementBySharebasedPaymentAwardFairValueAssumptionsExpectedTerm1us-gaap_truenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1falsefalsefalse00falsefalsefalse2falsefalsefalse00falsefalsefalse3falsefalsefalse008 yearsfalsefalsefalsexbrli:durationItemTypenaExpected term of share-based compensation awards, in 'PnYnMnDTnHnMnS' format, for example, 'P1Y5M13D' represents the reported fact of one year, five months, and thirteen days.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SAB TOPIC 14.D.2) -URI http://asc.fasb.org/extlink&oid=27013229&loc=d3e301413-122809 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (f)(2)(i) -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5070-113901 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Staff Accounting Bulletin (SAB) -Number Topic 14 -Section D -Subsection 2 false0Expected life11false 5us-gaap_EmployeeServiceShareBasedCompensationNonvestedAwardsTotalCompensationCostNotYetRecognizedus-gaap_truedebitinstantfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1truefalsefalse262000262000USD$falsetruefalse2falsefalsefalse00falsefalsefalse3truefalsefalse262000262000USD$falsetruefalsexbrli:monetaryItemTypemonetaryUnrecognized cost of unvested share-based compensation awards.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (i) -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5070-113901 false2Unrecognized compensation expense to be recognized over the remaining life of outstanding options12false 5us-gaap_SharebasedCompensationArrangementBySharebasedPaymentAwardOptionsVestedNumberOfSharesus-gaap_truenadurationfalsefalsefalsefalsefalsefalsefalsefalselabel1falsefalsefalse00falsefalsefalse2falsefalsefalse00falsefalsefalse3truefalsefalse115987115987falsefalsefalsexbrli:sharesItemTypesharesNumber of options vested.No definition available.false1Share-based Compensation Arrangement by Share-based Payment Award, Options, Vested, Number of SharesfalseStock Based Compensation (Details Textual) (USD $)NoRoundingNoRoundingUnKnownUnKnowntruefalsefalseSheethttp://www.dcbfinancialcorp.com/role/StockBasedCompensationDetailsTextual312
