On-Balance Volume

On-Balance Volume (OBV) attempts to identify price levels where position accumulation is taking place. Similar in purpose and interpretation to Accumulation/Distribution. Part of a group of trading indicators commonly referred to as "Oscillators" (other oscillators include Relative Strength Index, and Accumulation/Distribution), OBV provides confirmation and divergence information. Most analysis of OBV states that the value of OBV isn't as important as the slope of the line resulting from plotting OBV over time. 
Popularization of On-Balance Volume is credited to Joseph Granville in his 1963 book "Granville's New Key to Stock Market Profits", with preceding work by Woods and Vignolia in the late 1940's. 
==Calculating On-Balance Volume==
If today's closing price > previous session close then: 
 OBV = previous session's OBV + today's volume
If today's closing price < previous session close then: 
 OBV = previous session's OBV - today's volume
If today's closing price is the same as yesterday then: 
 OBV = previous session's OBV

On-chain

"On-chain," as opposed to "off-chain," is a technical term referring to blockchain technology. A piece of technology that is "on-chain" is something that directly affects how a blockchain manages storage space, processes transactions, or similar functions. Examples of this include increasing the block size of a blockchain, or sharding. 
On-chain also refers to transactions involving cryptocurrency that involve moving the cryptocurrency from one wallet to another and are thus recorded on the blockchain.

On-the-Run U.S. Treasury futures

== Notes ==
CME Group was scheduled to launch On-the-Run (OTR) U.S. Treasury Futures on Oct. 25, 2010. The contracts would be aimed at providing market participants with efficient and cost-effective price exposure to 2-Year, 5-Year, and 10-Year U.S. Treasury on-the-run yields. The new contracts will be listed with, and subject to, the rules and regulations of the CBOT.
OTR U.S. Treasury futures are cash-settled based on the yields of the most recently auctioned Treasury securities, which are typically the most actively traded and serve as the primary benchmarks used in pricing many fixed income instruments.
Applications for the new contract include on-the-run yield curve strategies, as well as inter-commodity spread with CME Group’s existing U.S. Treasury, Eurodollar and Swap futures contracts.
Each expiry’s life cycle would match up to the underlying Treasury note’s life cycle as the "on-the-run" issue. Each expiry would be listed around the beginning of cash-market When Issued (WI) trading and will continue to trade after such Treasury note is auctioned, throughout the underlying note’s life as the "on-the-run" Treasury security. Trading in the expiry would terminate on the morning of the next new auction, approximately two hours before the underlying note would become the "old."
The OTR Treasury futures would trade in price and are cash-settled utilizing on-the-run Treasury yields on the last day of trading. The final settlement pricing formula transforms the underlying on-the-run Treasury yield into a price index, whose price dynamics resemble those of a hypothetical $100,000 face-value Treasury note paying a semi-annual coupon rate of 4 percent per annum. Final settlement occurs on the last trading day. OTR Treasury futures trade both open outcry and on CME Globex.

Onion Futures Act

Passed on August 28, 1958, the Onion Futures Act (7 U.S.C Chapter 1 § 13-1) banned the trading of futures contracts on onions in the United States. The law was the first (and only as of 2010) to ban the trading of futures contracts for a specific commodity. Violation of the law is considered a misdemeanor punishable by a fine of up to $5,000.
== History ==
On June 18, 1956, the Commodity Exchange Authority charged Vincent W. Kosuga, Sam S. Siegel and National Produce Distributors with manipulating (or attempting to manipulate) three contract months of onion futures. The charges included attempted upward manipulation and price stabilization manipulation, in addition to successful downward manipulation.
Following the charges, Congress held hearings to consider banning onion futures trading because of the alleged influence of market manipulators. Led by Michigan Congressman (and future President of the United States) Gerald Ford, the law passed in 1958 and remains in effect as of 2013.
== Controversy ==
A 1963 study, published in the Journal of Farm Economics by Stanford University professor Roger Gray, compared prices before and after the ban and concluded futures contracts actually helped to stabilize prices. However, a 1973 study, published in the USDA ERS Technical Bulletin by Aaron C. Johnson, concluded that the 1960s, when no futures contracts existed, showed the least volatility in onion prices on record.
The debate persists, as does volatility in onion prices. For example, between October 2006 and April 2007 onion prices increased 400%, decreasing 96% by March 2008 and increasing again by 300% by April 2008.

Ontology (ONT)

Ontology is the name for a public blockchain-based network as well as its native coin. ONT launched as a coin on the NEO blockchain.
Ontology launched its network after an airdrop of ONT coins to NEO holders in late June 2018. Ontology and NEO cooperate extensively although the full extent and nature of their relationship is unclear. On August 8, 2019, Ontology introduced OWallet to be used in conjunction with the transfer of ONT from the NEO blockchain to its own blockchain. 
Each ONT will continuously throw off another cryptocurrency ONG which is designed to be used by enterprises on the Ontology blockchain to operate business-level blockchains that can be customized to different applications.
According to CoinMarketCap, an online cryptocurrency data aggregator, ONT was the 22nd largest coin by market capitalization and the 30th most actively traded cryptocurrency in early February 2019. ONG's market capitalization was not available - presumably due to the ongoing dynamics of coin creation, although its traded volume was reported as the 156th most active.

Onyx Digital Assets

|- style="vertical-align:top;"
| style="height:100px; width:700px; text-align:left;" |
Onyx Digital Assets is JPMorgan Chase & Co.'s blockchain-based network for fixed income market trading. 
The bank established Onyx as a new business line with a staff of 100 in 2020. Onyx enables the bank to commercialize its blockchain and digital currency developments, including the newly launched JPM Coin. 
Onyx incorporates JPMorgan's interbank payment system, the Interbank Information Network (IIN), rebranded "Liink," according to the Onyx website. 
Earlier, in April 2019, JPMorgan head of global clearing John Hunter said with the IIN the bank was "looking at the ability to do more at the point of settlement" with blockchain technology. The IIN is a blockchain-based digital payments platform that had been set up in partnership with the Australian ANZ bank and the Royal Bank of Canada in 2017. 220 banks were included in the IIN by 2019. The IIN was useful in particular for correcting mistakes and errors in settlement instructions for interbank transfers. 
While reporting in September 2019 that Deutsche Bank, the world’s biggest clearer of euro denominated payments, had joined the IIN, JPMorgan noted that there were then 310 banks signed up to use the service.
