Open Interest (OI)
Open interest counts how many derivative contracts, futures or options, are currently live and unsettled. It is not trading volume, which tallies how many contracts changed hands in a day; open interest is the running total of positions still open, still to be closed out or settled.
Rising open interest means new money is flowing in and fresh positions are being built; falling open interest means positions are being closed and interest is draining away. Read alongside price, it hints at how much conviction is behind a move.
Example: A commodity rallies hard and open interest climbs right alongside it. Traders read that combination as a strong, well-supported uptrend, because new buyers are actively piling into fresh long positions rather than merely closing out old shorts. Had the price risen while open interest fell, the same rally would look weaker, more like short-sellers covering than genuine new demand, and far more likely to fizzle once the covering is done.
Open Market Operations
Open market operations are the central bank’s main day-to-day tool for steering interest rates. The mechanism is simple in principle: to loosen policy, the bank buys government securities from banks, pumping cash into the system and pushing rates down; to tighten, it sells them, draining cash and nudging rates up.
By adjusting the supply of reserves in the banking system this way, the central bank keeps its key short-term rate inside the target range it has set.
Example: A central bank wants to hold its policy rate at a chosen level. When market rates start drifting above target because cash is scarce, it steps in with open market operations, buying securities to inject reserves and ease the pressure back down. These operations happen quietly and routinely, the technical plumbing behind the headline rate decisions, and most of the time no one outside the money markets pays them any attention at all, even though they keep the whole system anchored.
Open position
An open position is any trade that has been entered and not yet closed, so it remains exposed to changes in the market price unless offset by another position. The moment you buy or sell and have not yet closed out, you hold an open position, and its value rises and falls with the price until it is closed, typically by making the opposite trade, or until it expires or is settled.
Open positions remain exposed to market risk; they gain and lose money in real time, tie up margin, and can trigger a margin call if they move too far against you.
Example: A trader buys ten thousand euros against the dollar and does nothing else. That is an open position, and its profit or loss swings with every tick of EUR/USD, showing up as unrealised gains or losses in her account. Only when she sells those euros back does the position close, realising the resulting profit or loss; until then it stays open, and its value can continue to fluctuate while the market is trading.
Open Source Software
Open source software is software whose underlying code is published for anyone to read, use, modify, and share, rather than kept locked away as a trade secret. The idea powers much of modern technology, from operating systems to web servers, and it sits at the very heart of cryptocurrency.
Bitcoin’s code is open source, which means anyone can inspect exactly how it works, verify there is no hidden trickery, and even copy it to launch their own coin. That transparency is a feature, not a flaw: trust comes from being able to check.
Example: When a new cryptocurrency launches, developers and skeptics alike can pull up its open source code to see whether it does what its founders claim, checking for backdoors, hidden coin allocations, or sloppy security. A project that keeps its code secret invites suspicion, whereas an open codebase lets the whole community audit it, which is why open source is close to an unwritten requirement for a credible crypto project.
Operation Twist
Operation Twist is a central-bank manoeuvre that reshapes the yield curve without printing new money. The Federal Reserve sells its shorter-dated government bonds and uses the proceeds to buy longer-dated ones, twisting the curve by pushing long-term yields down while letting short-term ones drift up.
Unlike quantitative easing, it does not expand the balance sheet; it just changes the mix of what the central bank holds. The aim is to lower long-term borrowing costs, mortgages and business loans, to support the economy.
Example: The Fed first used the tactic in the 1960s and revived it in 2011, selling short-term Treasuries and buying long-term ones to drag down long-dated yields when its key short-term rate was already near zero and could go no lower. For a bond trader, the announcement meant one thing: expect the long end of the curve to rally and the gap between short and long yields to narrow, exactly the twist the name describes.
Option expiry date/price
An open position is any trade you are still in, live and exposed to the market’s every move. The moment you buy or sell and have not yet closed out, you hold an open position, and its value rises and falls with the price until you finally exit by doing the opposite trade.
Open positions are where all the risk lives; they gain and lose money in real time, tie up margin, and can trigger a margin call if they move too far against you.
Example: A trader buys ten thousand euros against the dollar and does nothing else. That is an open position, and its profit or loss swings with every tick of EUR/USD, showing up as unrealised gains or losses in her account. Only when she sells those euros back does the position close, locking in the result; until then it stays open, and anything can still happen to it while the market is trading.
