Lay and Back in Running

[charlespeter]

I'm new and wonder if someone can help. I want to implement a simple strategy that I can test on horse racing. I have created a bot that places a lay bet on each runner that fulfills a certain qualification e.g. no lower than 2.0 odds and places the bet for a liability. I want the bot to place a lay bet and offset that bet with a back bet at a certain number of ticks. This I have managed to do.

The problem that I have is that the bot keeps firing lay bets into the market before the original trade is complete thus doubling or even tripling the liability on the runner where there is an open trade. I have tried two things: unmatched bet condition must be < 1 which seems to stop every selection from firing until every unmatched trade is completed which isn't what I want or unmatched bets = 0 which appears to have no effect.

I know I'm doing something wrong and wonder if Dallas or someone can help me please

Many thanks

Check your unmatched bets condition it sounds like you have set it to look at the market and not a individual selection, it should be

"Unmatched bets"
On Selection
is "Equal" to 0

Also if using it IR make sure your re-arm time is 2 secs or greater (3 secs if using below the min £2 stakes) to allow enough time for your bet to appear in the market before the next triggers.
