In order to help prevent the entry of erroneous price or quantity values in the Order Entry window and Order Load panel, you can set threshold amounts. If you attempt to enter values higher than the threshold amount, a warning dialog box appears confirming the amount you entered is correct. This is also known as the "Fat Finger Warning". The Fat Finger warning is meant only to catch the accidental entry of values.
For example, you can set a maximum threshold amount of 200,000 shares. If you attempt to purchase more than 200,000 shares, a warning dialog box (similar to the following) appears asking you whether to proceed with the order.
NOTE: The amount for the Fat Finger Warning is meant only to display a warning and will not change the maximum number of shares you an purchase according to your account ID. The Fat Finger Warning will not prevent you from placing an order using a value higher than the warning amount.
Perform the following to set price and quantity threshold amounts:
From the Main menu, select Tools>Settings. The Settings window - Alarms tab appears
Click the Order Entry tab
Perform one or more of the following
From the Quantity section - Warn if Exceeds field, type the maximum allowable quantity
From the Price section - Warn if Exceeds field, type the maximum allowable price
From the Price
section - Warn if Off By % field, type the maximum allowable percentage
amount. Use this field when placing Limit orders to specify the maximum
percentage ABOVE the ASK when buying and the maximum percentage BELOW
the BID when selling. This option affects the amounts typed into the Price field on the Order
Entry window and Order Load
panel .
Click OK to save the settings and close the window
