Guardian Automation: NSW-Markets - Close Trade In-Play by Laying Only
I guess this is my beat now.
The easiest was is to have your opening bet a back bet.
If your opening bet is a lay bet, then in theory you can close the trade with lay bets only by laying every other horse for the relevant weighted amount but I can't imagine being able to do that In Play when the spreads are so wide and the markets so thin. You could try doing it with reverse trades but you'll have a lot of vol in your pnl.
Anbell, thanks again! In order to avoid the turnover charge of 2.4% of total back bets, I religiously stick to lay bets only. Would like to know of smart ways to close bets in less liquid markets.
