 We heard the term analogue trading. That was maybe how it was done in the 80s and 90s. What is analogue trading? London International Financial Futures Exchange is a mouthful. Hung with the, yeah. That was a very serious open outcry market based on the ones that they had in Chicago. So yeah, it was so analogue that you would stand in a hexagonal pit and shout at people in order to execute a trade. And when you executed the trade, you wrote it on a piece of card and flicked it to your clerk who would be standing around the edge and he'd run off and then put input into the exchange system so that the trade could be matched with the counterparty. It was all done with hand signals. So you would do the contracts on the face and the price out here. So if you wanted to pay, you know, 25 for 52 contracts, then that's how you signaled to the guy.
