This is the third in a series of articles that started Monday, October 23, 2006 with an article entitled “Limit Orders & Market Orders”.
One Sends The Other (OSO)
This is used to send a second order contingent on another order being filled.
For example, let’s say you intend to buy. And if filled, you intend to enter a stop loss order. To carry out those intentions you can use this order, the OSO.
First you enter your buy order. That can be in the form of a lowball Limit Order or a Stop Limit Order. For example, you want to buy at 1350. To do that, enter “Buy at 1350 Limit”.
Second, if and only if the first order is filled, you send a Stop Market Order below the current price specifying the price at which you want your Stop Market Order to take effect. For example, you bought at 1350 and you want to limit your loss to 5 points. To do that, enter “Sell at 1345, Stop Market”.
Combining the two, you enter an OSO Order in which the Second order is sent if and when the First order is filled.
A major benefit of OSO Orders is that they relieve you from babysitting your First order. It enables you to put your trading on semi-automatic. Not every broker accepts OSO Orders.
One Cancels The Other (OCO)
This is used when you intend to enter two concurrent orders and intend that if one of them is filled, the other one is to be cancelled.
OCO orders are usually a pair of orders in the opposite direction of each other. For example, let’s say you know an important government report is going to be released tomorrow. You believe that the report will impact the market strongly but you don’t know in which direction. You want to buy if prices go up and you want to sell (short) if prices go down. To do that, you use an OCO order having two parts.
For example, let’s say the S&P futures today had a high of 1390 and a low of 1380. You expect a government report to come out tomorrow and you expect it to move the market one way or the other, but you don’t know which way. Therefore, you use an OCO order.
One part of it would be an order to “Buy 1391 Stop Limit 1392”. You want to buy if prices exceed yesterday’s high of 1390, in this case at 1391. You want to prevent yourself from getting a bad fill so you limit the maximum you’re willing to pay to 1392. You might not get filled, but you prefer that to an uneconomical fill.
The second part of this OCO order would be an order to “Sell 1379 Stop Limit 1378”. You want to sell (short) if prices fall below yesterday’s low of 1380, in this case at 1379. You want to prevent yourself from getting a bad fill so you limit the minimum you’re willing to sell to 1378. You might not get filled, but you prefer that to an uneconomical fill.
A major benefit of OCO Orders is that they enable you to put your trading on semi-automatic. Not every broker accepts OCO Orders.
More Combinations
You can even combine OSO and OCO orders in combinations limited only by your imagination.
However complicated order entry gets for trading eMini stock index futures, they’re not anywhere nearly as complex or have as colorful names as orders for trading options. There’s no eMini order equivalent of a Triple-Bypass-Condor Put-Call Strangle Option order!
We'll chat again soon ...
