Hello,

I'm testing something on yield spreads (futures, FYT, FOB, NOB) and have some basic question.

In attachment you can find transactions list, there is ICS with price and outright prices corresponding to that ICS. If I look at ICS I can see a profit. Saying it easiest way - selling ~ -0'012 (minus 0'012) and buying back at -0'017 (minus 0'017). Even just looking at ICS FYT ladder - selling higher buying back lower. But if I count it by outrights there is loss.

How it works exactly ?

The only thing that comes to my mind is that ets ratio for this (3:2) is not accurate for short time trading.

DV01 for 5y is 46,81$, 10y 79,89$, so we have 140,43 : 159,78.

From the ATR perspective (intraday 5 min) is 5y 4 tick, 10y 4 ticks
4*3*7,8125=93,75 to 4*2*15,625=125,
so 93,75$ (5y) : 125$ (10y).

This is the reason that I can see profit on ICS ladder but in fact I can have loss ?

I will be thankful for info.

Are you doing this in sim? I know at least one platforms (TT) simulated matching engine gives inaccurate underlying leg fills for a simulated fill in an ICS spread. I wouldn't be surprised if other vendors have the same problem.

In live trading in FYT you will capture at least $23.4375 per tick.
