Accounting Policies [Abstract]
Summary of Significant Accounting Policies	N ote 2. Summary of Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of only normal recurring adjustments, considered necessary for fair presentation have been included. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ended December 31, 2020 or any future period. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Risks and Uncertainties The COVID-19 pandemic continues to rapidly evolve and has adversely impacted global commercial activities. Management expects COVID-19 related changes in market and investor behaviors to impact our asset- and spread-based revenue. However, given the uncertainty around the duration and extent of the COVID-19 pandemic, management cannot predict the impact on the Company’s results of operations, financial condition or liquidity in the third quarter for 2020 and subsequent periods. Estimates and assumptions about future events and their effects on the Company cannot be determined with certainty and therefore require the exercise of judgment. The Company is not aware of any specific events or circumstances that would require the Company to update its estimates, assumptions and judgments or revise the carrying value of its assets or liabilities. The Company will update the estimates and assumptions underlying the consolidated financial statements in future periods as events and circumstances develop. Recent Accounting Pronouncements – Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted the new standard on January 1, 2020 using the modified retrospective transition method with certain available transitional practical expedients, and elected to apply the short-term lease exemption (described below) to all of its classes of underlying assets. The standard had a material impact on the Company’s condensed consolidated balance sheets, but did not have an impact on the Company’s condensed consolidated statements of comprehensive income. The most significant impact was due to the recognition of ROU assets and lease liabilities for operating leases. Adoption of the standard had no impact on previously reported results. The Company determines if an arrangement is a lease at inception. Operating leases are included in other current assets, operating lease ROU assets, accrued liabilities and other current liabilities, and long-term portion of operating lease liabilities on the Company’s condensed consolidated balance sheets. The Company does not have material finance leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligations to make payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the remaining lease term. The Company uses an estimated incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components. The Company has elected to use the practical expedient to exclude the non-lease component from the lease for all asset classes. The majority of the Company’s lease agreements are facility leases. The Company’s leases have a weighted-average lease term of 7.6 years and used a weighted-average discount rate of 3.63% as of June 30, 2020. Future minimum lease payments under non-cancellable leases as of June 30, 2020 is as follows: Remainder of 2020 $ 2,225 2021 5,525 2022 5,872 2023 5,710 2024 6,084 2025 and thereafter 19,671 Total $ 45,087 In January 2017, the FASB issued ASU 2017-04, Intangibles, Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment, which removes step 2 from the goodwill impairment test. As a result, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. In July 2018, the FASB issued ASU 2018-11, Lease (Topic 842) Targeted Improvements, which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing transactions. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles, Goodwill and Other, Internal-Use Software (Subtopic 350-40), which provides guidance to evaluate the accounting for fees paid by a customer in a cloud computing arrangement. If a cloud computing arrangement includes a license to internal-use-software, then the software license is accounted for by the customer in accordance with Subtopic ASC 350-40. An intangible asset is recognized for the software license and a liability also recognized. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. In October 2018, the FASB issued ASU 2018-17, Consolidation, Targeted Improvements to Related Party Guidance for Variable Interest Entities, which clarifies the determination as to whether a decision-making fee is a variable interest by requiring reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as an equivalent of a direct interest in its entirety. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. Recent Accounting Pronouncements – Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and improves consistent application of U.S. GAAP by clarifying and amending existing guidance. The new standard is effective for the Company on January 1, 2021, with early adoption permitted. The Company is currently evaluating the effect that ASU 2019-12 will have on its consolidated financial statements.

Earnings Per Share [Abstract]
Net Income Per Share Attributable to Common Stockholders	Note 14. Net Income Per Share Attributable to Common Stockholders Basic net income per share is computed by dividing net income attributable to common stockholders by the basic weighted average number of shares of common stock outstanding for the period. For the calculation of diluted net income per share, the basic weighted average number of shares of common stock outstanding is increased by the dilutive effect (if any) of stock options, restricted stock awards and restricted stock units. The following table provides a reconciliation of the numerators and denominators used in computing basic and diluted net income per share attributable to common stockholders: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Net income (loss) attributable to common stockholders $ (9,280 ) $ 3,237 $ (6,544 ) $ 6,048 Weighted average number of shares of common stock used in computing net income (loss) per share attributable to common stockholders, basic and diluted 67,208,746 66,150,000 67,175,603 66,150,000 Net income (loss) per share attributable to common stockholders, basic and diluted $ (0.14 ) $ 0.05 $ (0.10 ) $ 0.09 The following securities were not included in the computation of diluted shares outstanding because such securities did not have a dilutive effect.

Accounting Policies [Abstract]
Risks and Uncertainties	Risks and Uncertainties The COVID-19 pandemic continues to rapidly evolve and has adversely impacted global commercial activities. Management expects COVID-19 related changes in market and investor behaviors to impact our asset- and spread-based revenue. However, given the uncertainty around the duration and extent of the COVID-19 pandemic, management cannot predict the impact on the Company’s results of operations, financial condition or liquidity in the third quarter for 2020 and subsequent periods. Estimates and assumptions about future events and their effects on the Company cannot be determined with certainty and therefore require the exercise of judgment. The Company is not aware of any specific events or circumstances that would require the Company to update its estimates, assumptions and judgments or revise the carrying value of its assets or liabilities. The Company will update the estimates and assumptions underlying the consolidated financial statements in future periods as events and circumstances develop.
Recent Accounting Pronouncements	Recent Accounting Pronouncements – Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted the new standard on January 1, 2020 using the modified retrospective transition method with certain available transitional practical expedients, and elected to apply the short-term lease exemption (described below) to all of its classes of underlying assets. The standard had a material impact on the Company’s condensed consolidated balance sheets, but did not have an impact on the Company’s condensed consolidated statements of comprehensive income. The most significant impact was due to the recognition of ROU assets and lease liabilities for operating leases. Adoption of the standard had no impact on previously reported results. The Company determines if an arrangement is a lease at inception. Operating leases are included in other current assets, operating lease ROU assets, accrued liabilities and other current liabilities, and long-term portion of operating lease liabilities on the Company’s condensed consolidated balance sheets. The Company does not have material finance leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligations to make payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the remaining lease term. The Company uses an estimated incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components. The Company has elected to use the practical expedient to exclude the non-lease component from the lease for all asset classes. The majority of the Company’s lease agreements are facility leases. The Company’s leases have a weighted-average lease term of 7.6 years and used a weighted-average discount rate of 3.63% as of June 30, 2020. Future minimum lease payments under non-cancellable leases as of June 30, 2020 is as follows: Remainder of 2020 $ 2,225 2021 5,525 2022 5,872 2023 5,710 2024 6,084 2025 and thereafter 19,671 Total $ 45,087 In January 2017, the FASB issued ASU 2017-04, Intangibles, Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment, which removes step 2 from the goodwill impairment test. As a result, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. In July 2018, the FASB issued ASU 2018-11, Lease (Topic 842) Targeted Improvements, which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing transactions. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles, Goodwill and Other, Internal-Use Software (Subtopic 350-40), which provides guidance to evaluate the accounting for fees paid by a customer in a cloud computing arrangement. If a cloud computing arrangement includes a license to internal-use-software, then the software license is accounted for by the customer in accordance with Subtopic ASC 350-40. An intangible asset is recognized for the software license and a liability also recognized. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. In October 2018, the FASB issued ASU 2018-17, Consolidation, Targeted Improvements to Related Party Guidance for Variable Interest Entities, which clarifies the determination as to whether a decision-making fee is a variable interest by requiring reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as an equivalent of a direct interest in its entirety. The Company adopted the ASU on January 1, 2020 and it did not have a significant impact on the Company’s consolidated financial statements and related disclosures. Recent Accounting Pronouncements – Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles in Topic 740 and improves consistent application of U.S. GAAP by clarifying and amending existing guidance. The new standard is effective for the Company on January 1, 2021, with early adoption permitted. The Company is currently evaluating the effect that ASU 2019-12 will have on its consolidated financial statements.
