 So the guys on the phone with the brokers, they might be on the phone to banks and hedge funds. The guy in the booth would be like, okay, he'd give them the price. So we'd ask the broker on the edge of the pit, what's the size of the bond? That meant size. And so, let's say it was 2,3, 2,3, for example, he'd be like 2,3, 2,3, 2,3, and he'd be like size, he'd be like bid on 200 and 500 and offered in 500. That was the size when your arm. So you just couldn't shout. So this guy would get on the phone, he'd be like going, okay, it's 2,3, bid for a, you know, 200 offered in 500 and he might say, well, buy 400. So he'd go, I ain't 400. So guy on the edge of the pit, would then be like buy 100, buy 100, buy 100, buy 100, from let's say he traded with four different people. The trader in the middle, which would be someone like me, I would be the market maker. We'd be like, okay, I'll say you're 100. And then I'd write down sold 100. And then I'd give my card to my clerk, he would give his card to his clerk and then we'd all matched up on the internal computer system. So that was analog trading.
