Tested the new bot here - LayBackSet1WinnerDelays.baf

With the time delays. Seems to have triggered all correctly with delays and skews on the Williams match yest (Practice mode, def not one of my picks).

Issue I have found is sometimes the lay bet might not get fully matched due to price movement. So maybe only half my stake is risked. Anyone know how to remedy this?

If you still not solved skew 60/40 ,that's a simple math how to calculate stake that should be backed on 2nd set winner ( Guessed already market is greened in profit after 2nd set )

If p/l on selection = P ( after hedging )

Odds on 2nd set winner = ODDS

Back Stake on 2nd set winner = P / ( 2 * ODDS + 1 )

and that's it... skewing 60 / 40 profit leave on 2nd set winner.


Example - hedged in profit +£ 40 on both players

2nd set winner odds = 1,8

Back Stake on 2nd set winner = 40 / ( 2 × 1.8 + 1 ) = 40 / 4.6 ~ £ 8.70

Fast check :

Profit on 2nd set loser = £ 40 - £ 8.70 = £ 31.30

Profit on 2nd set winner = £ 40 + £ 8.70 × 1.8 = £ 40 + £ 6.96 = £ 46.96

Last check : £ 31.30 / 4 ~ £ 7.83 × 6 = £ 46.98

Error is true ;)

Whoosh - Is the sound it has made going over my head lol. I'm reading this a few times and not sure how this translates into the 'stored value we set at 90%'. Completely goes over my head.

Just build 3 SVs

SV1 = odds * 2
SV2 = SV1 + 1
SV3 = P / SV2 and that's it :D

And make sure by conditions that you back on 2nd set winner and not on any player...

That's gone in a little better. Thanks. Skewing is working no prob on the bot currently.

Place the bet at 2nd or 3rd best market price to increase the chances of it being fully matched
Still an issue on the lay bet side for some of the matches this eve. Do you recommend putting on a slight delay for market to settle (This helped on the greening at end of the 1st set). Or is there a setting i'm missing that asks the bot to match at best price?
