sorry for bad english tomorrow i was trading on market "winner us masters 2017, golf". I was making 'lay' for all sportsmen in market and cashout on market was +600$. I lay Dustin J. 5500$ and when all bets with him was cancelled from 600 i saw -4900. Take back D.J. with coefficient 1000 like on all other sportmarkets or u must cancel all this market. And what will you do if 5 or 10 sportsmen will take off tournament before it begining? then i will saw -25000 instead of -4900? How now i can trade on betfair if you can cancel any result or player or team? why there are not same cancels on horse riding or F1 or football? On this markets always coef.1000 or recalculation if sportsman is out. Betfair is exchange or a simple betting service now?
There has never been a reduction factor on the golf. Same with the bookies as on here. Put it down to experience and move on. Not every week the short price fave drops out.
