TAS/EDE relative values, page-77

Is it possible to actually make a trade at those ratios. As I see it you can buy TAS at 16.5c (only if you will settle for 30.869) and you would have to pay 20c for EDE. that is a ratio of 1.219. However if you want to sell TAS you would get 16c and you would pay 20c for the EDE that makes the ratio 1.25 to 1.

Fractions of a cent can make a big difference. Timing is the key or you can sell and not buy or buy and not sell. for instance if you bought EDE at the top today 21.5c and then the Trump results came in and you sold TAS at 16c to pay for them the ratio
becomes 1.343 to 1. On the other hand if you sold TAS at the top of 17.5c and bought EDE post the Trump panic at 19.5c then the ratio would have been 1.1107 to 1.

So ratios should be calculated on the ability to actually make the trade.
