Tick Conditional bets under Display columns in preferences to display a new column in the standard Market Grid or to the right of the Ladder Grid.

Click on the C next to the required selection to add a conditional bet for that selection.

In the above screenshot "Titus Gents" will be backed at the best back price minus one tick if the best back price is less than or equal to 2.00.
"Ajjaadd" will be layed at the best lay price if the best lay price is between 1.50 and 2.50 inclusive. The Price 2 column is only used when using the between condition.

When you have entered your criteria tick the Active column to enable the bet to be placed if the criteria are met. Notice that the background colour of the C column is blue for active conditional bets.
If the criteria are met and a bet is placed then the Active column will automatically be unticked.

If you change the criteria while the Active column is ticked then it will be unticked automatically so you will need to remember to tick it again afterwards.

Enter a value in the max liability box to limit your liability, bets will not be placed if the liability of that individual bet (not based on your overall P&L) exceeds the liability entered.
Enter 0 or blank as the liability to ignore max liability.

Use the Trigger after column to set a time to begin evaluating your criteria.

Tick the "Allow bets to be placed in play" if you are happy for the bets to submitted after the market has been turned in play.

Click Apply current settings to entire field and the criteria will be copied to all the other selections in the market, if an entry already exists for the other selections then a new entry will be added, the existing entry will not be overwritten.

Click Add new entry for current selection to create a new entry for the current selection, the criteria will not be copied.

When you have an active Conditional Bet for a given selection you will see that the Conditional Bets column in the Grid has a blue background to signify this (as pictured above).

IMPORTANT: Conditional bets will only be active while you have the market open. If you subsequently change to another market in the same tab page then the conditional bet will not be retained and therefore never triggered. If you need to have conditional bets on multiple markets you need to open a separate tab page or create a coupon view for each market and leave them open.
