O

One cancels the other (OCO)

An order type that allows traders to place two orders simultaneously, with one being cancelled if the other is executed.

One cancels the other order (OCO)

On top is trading slang for dealing at the very best price currently showing, joining the top of the market rather than waiting behind it. In voice broking especially, a trader who goes on top is matching the best bid or offer already on the screen, putting their order right at the front of the queue at that price.

It signals urgency, a willingness to trade now at the prevailing level rather than hold out for something better.

Example: A broker is showing the best offer in a bond at a certain price, and a buyer who wants in without delay says he’ll go on top, placing his bid at that same best level to get done immediately rather than pitching lower and risking the market running away from him. Being on top means accepting the current price as good enough and prioritising getting the trade filled over squeezing out a marginally better one.

One touch

An OCO ties two orders together so that the moment one fills, the other vanishes. Short for one-cancels-the-other, it is a way to bracket a position with two exits, or two entries, without risking both being triggered. The classic use is pairing a take-profit order above the market with a stop-loss below it: whichever the price hits first executes, and the platform automatically kills the other, so you are never left with a stray order still live after you have already exited.

Example: A trader is long a stock at 100. She sets an OCO with a take-profit at 110 and a stop-loss at 95. If the stock climbs to 110, that order sells her out for a profit and the 95 stop is cancelled on the spot; if instead it drops to 95, the stop fires and the 110 target disappears, so she can walk away from the screen knowing only one of the two can ever execute.

One Triggers Other (OTO)

An OTO, or one triggers other, is a pair of orders where the first, once filled, automatically places the second. Unlike an OCO, where two orders sit live together and one cancels the other, an OTO is sequential: nothing happens with the second order until the first has actually executed.

It is a way to set up an entry and its follow-on exits in a single step, so you do not have to be watching the moment your entry fills.

Example: A trader wants to buy a stock only if it dips to 95, and then, once she owns it, to protect it with a stop and a target. She builds an OTO: the primary order is a buy at 95, and attached to it is a bracket that springs to life the instant that buy fills, placing her stop-loss and take-profit automatically. If the stock never reaches 95, nothing triggers and no exit orders are ever created.

OPEC+

OPEC+ is the wider oil alliance, the original OPEC cartel plus a group of non-member producers who agreed to coordinate with it, Russia the largest among them. Formed in 2016 as oil prices languished, the arrangement gave the producers more collective muscle over supply than OPEC alone could muster, since the add-on members pump a big share of the world’s crude.

When OPEC+ agrees to cut or raise output, it is trying to steer the global oil price by managing how many barrels reach the market.

Example: With prices sagging, OPEC+ announces a coordinated production cut of a couple of million barrels a day. Traders react at once, bidding crude higher on the prospect of tighter supply, and the decision reverberates through fuel prices and inflation worldwide. The catch is discipline: the deal only works if members actually stick to their quotas, and suspicion that someone is quietly overproducing can undercut the very price impact the group was aiming for.
