So this post will probably create some discussion!
Up until now my bot has been taking "Best Market Price", as backtesting showed it marginally better than offering Reverse, however my backtesting cannot accurately simulate offering. So today I thought I would try using Reverse price offers, and an interesting result from watching the bot... So far today it's only done 7 trades and is -£1.15. However, it has "offered" another 7 trades that didn't match and the price action went on to what would have been a decent win... Hmmm, it would have been in profit today if I hadn't switched.
So the motto for the day "Don't fiddle with your bot"(!)
Trading What I see !?

Yep that's the dilemma, the only offers with a 100% fill guarantee are the ones that go against you. Couple of possibles..... Don't join the back of a big offer queue (take or offer based on queue size) or have a fill/kill on the offer and either move it or just take if it's not filled. Or...... look at whether the missed moves actually make up for missed tick or not. Or...... 
..... Derive some sort of noise metric and decide based on that, more noise = better fill possibility. I'm sure there's others, there always is.

Tips yes. Great, maybe not so much.
When you've spent several years eating, breathing and sleeping these questions then you have some ideas on file. The fact I'm still eating, breathing and sleeping these questions means they haven't necessarily always been good ones.
Each strategy has its own logic, but count me in for Best Reverse for most of them.
If you consider your long-term expected PoT (perhaps 5%?) and then consider the difference in the spread between BMP and Best Reverse (perhaps 2.5%?) - there's a pretty compelling reason to use BestReverse most of the time.

Ive turned live trade off now, convinced this is a dud! going to see how backtesting goes this week..

I think you may have speculated about the influence of LLHF bots....75% of traffic and revenue.
200K RPS ain't too shabble from the Betfair end tbh esp as they also peak at approx 10k/s orders with a response time of no more than 8ms.

Interesting statistics. By "Trader Bots" they mean not only software (Bet Angel and others) but all existing bots I guess? If so, it will be interesting to know the statistics for bots made for "personal use".ShaunWhite wrote: ↑Fri Apr 02, 2021 2:37 amI think you may have speculated about the influence of LLHF bots....75% of traffic and revenue.

Thank you, Shaun. I've been stalking from thread to thread for a week in a hope that someone will notice it
.I wanted to draw "BF" on that box at first, but then thought about PC2 and I'm not quite sure who's the box and who's Mario now.
I like yours too, reminds me my childhoods robot toy, sweet memories

That one's maybe from the 80's, about 3" tall and by a company called Yone. I went through a phase of collecting them a few years ago but prices get a bit eye-watering for the interesting 60s Japanese ones. They're in the loft now with the rest of my pension "investments" (aka junk I had to justify spending the money on)

The one I had wasn't that big it was a smaller one, all red. It was probably a rip off of the one you had!
It was still one of my prized possessions as a kid along with my Snoopy game
