How To Hire A Coach
18:52

Peter WhiteHOST
Jamie, what do you think to all that about the attitude, the presence, the character over the coaching?
J
18:59Jamie WaltonGUEST
I've just kind of been listening to all the different skill sets that you've just listed.
J
19:09Jamie WaltonGUEST
You have to have someone who's highly empathetic, doesn't take any shit, can manage a class, can be a source of credibility.
J
19:20Jamie WaltonGUEST
So I don't think we've even mentioned the benefit of the coach being able to... jump up on the rings and do five beautiful ring muscle-ups, the amount of credibility that gives and the ability for that coach to command the room, we talk about it not being a total necessity.

Launching Specialist Classes - Jamie Walton and Jonny Davies
22:05

Jonny DaviesGUEST
affects on thursday yes weightlifting on friday yes gymnastics midweek no weightlifting midweek no So sometimes is the answer to that question.
J
22:15Jamie WaltonGUEST
And I suppose the benefit is saying that, well, we're playing the long game on this.
J
22:36Jamie WaltonGUEST
But the long game would be, okay, well, this person's gonna be more engaged, they're gonna get more progress, they're gonna have a higher average lifetime value, they're gonna do all that stuff.

Jonny DaviesGUEST
They're very, very, very good at, like, if you think it needs something, you can just request and then we'll check it
How I Bought My Gym - Jamie Walton
J
22:51Jamie WaltonGUEST
Um, she got the train from Brighton to London, got the train from London to Newcastle, and then a taxi from the middle of Newcastle up to Method in the morning, and then she walked around the site with us for, like, half an hour, and then off she went on her way, and I was like, "Oh, yeah, she's fine.
J
23:09Jamie WaltonGUEST
Yeah, she seems happy." And then she sent back a report that, like, we needed to do so much.

Electronic Trading Strategies - Dr Jamie Walton
J
18:00Jamie WaltonGUEST
I can't actually... make money from taking it but if i make my market now i just say i'm seven at nine and someone gives me at seven Now that's a much bigger advantage.
J
18:12Jamie WaltonGUEST
So overlaying a signal in market making, if it's correct, can be very powerful because it gives you the position, your alpha, without having to cross the spread.

Electronic Market Making Part 2: The Algorithmic Perspective - Dr Jamie Walton
3:53
7:17

David CoxHOST
You've had this for a while, but in a lot of other markets, less so, I think, if I'm understanding correctly.
J
4:00Jamie WaltonGUEST
Anything exchange traded or things like treasuries, of course, they're very liquid, very electronically traded.
J
4:07Jamie WaltonGUEST
It's normally where things are mostly electronically traded, you see this growth of algorithms being used to execute things.
J
4:14Jamie WaltonGUEST
So why do we want to use an algorithm rather than just trade in one go? Well, I mean, the main reason is to do with our old foe, market impact.
J
4:26Jamie WaltonGUEST
So if you were to trade in the market in large size, you would cause the market to move.

David CoxHOST
Yeah, so there is execution risk in the sense that if the market suddenly moves or some unexpected event which moves prices, then you may not get filled on those orders if they're all put in as a sort of limit order.
