MidPrice order

A MidPrice order is designed to split the difference between the bid and ask prices and fill at the current midpoint of the National Best Bid and Offer – the NBBO – or better.

You may also set a price cap to define the highest price (for a buy order) or the lowest price (for a sell order) that you are willing to accept.

Creating a MidPrice order in TWS Mosaic

Here’s how it works using Mosaic:

Click on a desired ticker symbol, then select to either buy or sell, and choose the number of shares you want to trade.

To the right of the price display you will see an algo dropdown menu with Adaptive set as the default.

Click on the arrow to the right of the word Adaptive and select MidPrice.

*Tip: You can select MidPrice in Order Type dropdown menu too.

You will notice that when activated, the MidPrice button displays a green light in it.

To its right is a Price Cap field, which by default states the word NONE.

This is effectively the limit price for your order, above which a buy order will stop attempting to buy, and below which a sell order will stop attempting to sell.

Let’s enter a price cap for this order.

Choose the appropriate time-in-force designation from the TIF field to the right.

You can now submit your order by clicking the Submit button.

Check the details on the Order Confirmation window and when ready, click Transmit.

Locating MidPrice orders within the Activity panel

The Orders tab in the Activity panel will provide you with an update on your open order, and details on filled orders will display on the Trades tab.

Now that you know how to create a MidPrice order in Mosaic, you may also want to watch the Traders’ Academy course on TWS Algos.

Let’s now turn our attention to the next lesson on order types in Traders’ Academy.
