What's the best BOT for a starter?

If you only know enough to ask that question, I'm guessing you're not ready for a bot.   It's like the CIA. It's no good you asking whether you can join the CIA. But if you have the abilities then you will be found...

Brie on toast is ok for a starter

Actually Milo, my reply to you was quite serious!! (If, paradoxically, also slightly flippant...)

That was my succinct answer. Here's something a little more long-winded...

A bot should be pretty much automated. You give it its orders and it goes off and makes you money while you go elsewhere - it's well worth keeping tabs on (with alerts, if necessary), just in case the bot is getting butchered by a superior creation. But, generally speaking, you'll let the bot go off and do its own thing without much surveillance needed from you.   

Given that a working bot apparently requires so little of your time, why on earth do you think that anyone with a working bot would sell it to somebody else? If it was as easy as buying an off-the-shelf newbie bot and letting it go, don't you think most people on Betfair would be operating bots and making money?  (And if that ever happened, clever engineers would quickly create superior bots that could beat the newbie bots to the punch, and the newbie bots would suddenly become unprofitable anyway.)

I can appreciate that there are winning strategies which, frankly, take up so much time relative to their profit, that many winning punters discard them due to those strategies not being worth the effort. However, there's absolutely no logic whatsoever in anyone selling a working bot, given that the bot can sit making money for them without them having to lift a finger. Anyone else using that same bot in the same market is likely to cut into their profit levels, so why sell the bot? Just set it working in as many markets as it appears to do well in. Spend the rest of the time constructing more sophisticated bots to take over from it when, inevitably, a better bot comes along to grind its little metal head into the ground.

There is no such thing as a good bot for newbies. Any off the shelf bot will be so simple that its techniques are already being bettered by better engineered models. You need to think of a strong strategy that a bot might be able to implement (which is where much of the skill comes in). If you can't program then there are ways round that, but any serious bot engineer will probably want to learn at least one programming language (Excel VBA, for instance). That'll help the thought process that goes into devising bot strategies, if nothing else.   

The key thing is that you need to know what it is that you want the bot to do that'll give your bot an edge over the other bot engineers - many of whom are amongst the smartest on Betfair. If you can work out that, the rest should be relatively straightforward. Hence my comment that, essentially, if you're ready to become a botter, you won't need to ask how.    If you want practical advice, learn to program. It's interesting and a great skill to have, even if you don't, ultimately, create any bots. If that sounds like too much effort, then I wouldn't bother going on with this.

Milo, I get the impression you're looking for advice on which API software to use rather than which bot? (which is often a confused point).

If you can pick value selections for the day, you might want to look at betsender bot. It can easily import your bets from Excel file.

i suspect trevh is right.

a bot is a piece of software that bets automatically with no intervention from a user.

the API is the method of accessing the site in a supported manner through software. so a bot would use the API to access the site.

there are plenty of software solutions, which are not bots, which access the site using the API, offering enhanced functionality over the website. I suspect this is what you want.

as for security, you are more secure using verified software that accesses the site via the API than you are accessing the website, as there is no risk of side-jacking as everything goes via HTTPS.
