This is the pertinent information traders should know about odd lot orders:

• An odd lot is a number of shares less than 100 (1-99)
• A "Round Lot" is 100 shares of stock
• Any number of shares that is a multiple of 100 is a round lot (i.e. 100, 600, 1,600, etc)
• An order for a number of shares greater than 100, but not a multiple of 100 (i.e. 142, 373, 1,948, etc) is a "Mixed Lot" (AKA PRL, or partial round lot, order)
• Odd-Lot orders are not posted to the bid/ask data on exchanges
• Odd-Lot orders are taken into the order book at the exchange they are routed to.  When the exchange is able to match an order from the other side of the book with the odd-lot, it will be filled.  This could lead to delay on execution of an odd-lot. 
• There are numerous guidelines for the routing of odd-lot orders:  Odd-Lot orders to initiate positions will not be routed to primary exchanges; Odd-Lot orders can be routed to primary exchanges, but only if the order in question is to close out a preexisting position; IB will not direct-route odd-lot orders which initiate positions to primary exchanges, therefore these type of orders should be Smart Routed so that IB's routing system can send the order to an ECN for execution.  The exception is that odd lots can be routed to NYSE/ARCA/AMEX, but only as part of a basket order or as a market-on-close (MOC) order.
• A mixed lot or PRL (i.e. 257 shares) direct-routed to NYSE/AMEX will be submitted in whole to the exchange (applies to both market and limit orders).  If the order is direct-routed to NYSE/ARCA, only the round lot portion of the order will be submitted and, if it is executed, the IB system will cancel the remaining odd-lot portion of the order.  If the order is routed via IB Smart Routing, all market centers are eligible to receive the order according to the Smart Routing logic (including NYSE/ARCA, but only for the round lot portion of the order).
• IB will not route odd-lot orders for HOLDRS.  The odd-lot portion of a PRL order for HOLDRS will be rejected by the IB system after the round lot portion of the order is executed.
• Individual exchanges may impose certain restrictions on odd lot orders, in addition to any of the restrictions mentioned above

1. Total Quantity – defines the aggregate order size (e.g., shares, contracts);
2. Trade Increment – defines the unit (e.g., shares, contracts) size for each component order;
3. Time Increment – defines the period of time (seconds, minutes or hours) between the submission of a component order and the submission of the following order;
4. Order Type – may select from market, limit or relative. A market order will be executed at the ask price and should only be used where, for example, a stock is highly liquid with significant bid-ask sizes. Limit and Relative order types require that the trader specify additional order relationships and the choices are numerous. The execution price, for example, may be specified as being relative to a fixed value, bid, ask or last price, VWAP, moving average or last trade. These choices may be increased or decreased by an offset factor and multiple conditions may be established. For example, one may wish to create a relative order type to match the bid price plus an offset factor of $0.01 and to ensure that they don’t lift the ask if the spread is $0.01, add a condition that the bid be no less that $0.02 beneath the ask price.
5. How to Operate – if the trader does not check the box titled “Wait for current order to fill before submitting next order” then orders which do not meet the price conditions will continue to accumulate in accordance with the established time increment, the unexecuted orders will be aggregated into one or more potentially sizable orders at the exchange. If this box is checked, then the more restrictive the buying conditions, the greater the likelihood that the algorithm will fall behind its schedule of buying or selling at every ‘X’ interval.  If this box is checked the trader may then check the box titled “Catch up in time”. When that box has been checked and should the algorithm fall behind, the next orders will be placed immediately after their predecessor fills until such time the algorithm has caught up.
6. Randomization – check boxes are provided to allow for a +/- 20% randomization in the time increment and a +/- 55% randomization in the trade increment. Accordingly, in the case of a 30 second time increment, this would allow for randomization of between 24 and 36 seconds between orders and in the case of a 500 share trade increment, this would allow for randomization of between 200 and 800 shares (rounded to the nearest round lot) per order. Randomization serves to minimize the likelihood of others detecting your order.
7. RTH – a check box is provided which will allow the order to be filled outside of regular trading hours.
8. Take up Offer Size – if a limit or relative order type is selected, the trader may input an order size which if bid (in the case of a sell order) or offered (in the case of a buy order) the trader would be willing to take in its entirety, up to the remaining portion of the total order quantity (satisfies the price conditions).

1. Price Range - traders may specify a price range outside of which they do not want to buy the stock;
2. News – the trader may stop the algorithm for some period of time if there is news on the stock, for example;
3. Position - traders may stop the algorithm based upon their position in the stock; For example, a trader running multiple algorithms one to buy the stock and another to sell in an attempt to trade the stock back and forth for a profit may decide to suspend one side if the position becomes substantially imbalanced;
4. Stock Path – a trader, for example, may wish to suspend the algorithm if a given moving average, say the 10-minute VWAP is not at least as high as another average, say the 50-day moving average. This feature enables you to set up algorithms to trade chart points even when you are not looking at the chart at that moment;
5. Stock Path for Multiple Symbols – this condition is similar to the last except that it calls for two symbols. Here you can put in any symbol and compare some data point regarding that symbol (e.g., 10-minute VWAP, etc.) to the same or a different data point regarding the second symbol. These comparative conditions can apply to different symbols or to the same symbol.   For example, you could specify that you want to buy a certain stock only if it has been in a continuous uptrend. So in addition to the 10-minute VWAP being higher than the 50-day moving average, you would also like the 10-day moving average to be higher than the 30-day moving average on this stock.
