How to calculate ZB bonds Premium collected into dollars for spreadsheet


I have recently started selling strangles on ZB US treasury bonds. I am trying to work out how to convert the 17/64 price I got to dollars for my spreadsheet. I am also trying to work out an excel formula to calculate the total premium collected for the short strangle trade. The price paid is as above.

above is the spreadsheet. I am trying to workout the total premium received in a excel formula.

The current formula I have for the Premium cell is =K6E631.25*0.5

if anyone can help that would be great. @exsanguinator

I log the decimal value. In the cell, I would type in “=17/64” which would calculate the decimal value of 0.265625. With ZB, 1 point = $1,000.

So premium formula would be “=K6 * E6 * 1000

ProTip: I use Google sheets and can import a csv url into a reference sheet. Tasty has a csv online with specs for futures. One can import this into a sheet and reference the cells for different calculations.

Perfect, thank you so much. Works perfect. First time trading bonds so was not sure how the calculations worked. I know you explained really well stop losses for me on another thread, that has help me trade safely. Regarding this ZB bond, how would you suggest I calculate a 2 x the premium stop loss. I use TWS.

I have 3 contracts. This would equal a premium of: 0.26562510003

= a premium of $796.99

When trading a new instrument, I recommend trading 1 lots before stepping up to multiple contracts.

Experiment with different stop loss parameters so you can find out for yourself exactly what you’re getting into. You’ll figure it out.
