QUESTION ABOUT SWAP INTEREST RATES WITH EXAMPLE

1

So, I have been using the formula below to calculate swap rate:

Swap = Lots*Open Price*Symbol swap rate (long or short)*1/(360*100)*contract size*quote currency to usd rate

Below are my calculations for several symbols:

 Time Type Symbol Lots Price Price long rate short   rate contract size day rate swap in Quote to usd rate swap in usd MT 4 Swap Ratio of MT4 Swap to Swap in usd 2016.01.11 14:03:24 buy eu50 1 3064.7 3080 -2.782 -3.218 0.1 -7.72778E-05 -0.023742438 1.0919 -0.03 -0.03 1.157212 2016.01.11 07:27:42 buy fr40 1 4324 4401 -2.782 -3.218 0.1 -7.72778E-05 -0.033712431 1.0919 -0.04 -0.04 1.086643 2016.01.11 16:05:31 sell uk100 2 5877 5949 -3.512 -2.488 0.1 -6.91111E-05 -0.0817308 1.4527 -0.12 -0.08 0.673796 2016.01.11 09:57:14 sell us30 10 16393 16455 -3.424 -2.576 0.1 -7.15556E-05 -1.175228444 1 -1.18 -1.17 0.995551

From the calculation shown above, we can see that the formula works for fr40 and us30, however it does not work on eu50 and uk100.

Any suggestions on how to calculate the swap rate?
