# Measuring liquiduity of a portoflio of bonds

I'm currently looking into applying bond liquidity out of curiousity.

The Method i'm currently using is the Barclays LCS score (live.barcap.com/publiccp/RSR/nyfipubs/barcap-email-mkting/qps/LCS_In-brief.pdf)

which states that a possible way to grade a bond liquidity is simply

$$Ask-Bid/Bid$$

What I do is I measure the spread

$$Ask-Bid$$

This is the part where I'm doubting i'm going the correct way.

I take a total of the entire spread and divide it by the spread of each asset to get a weighted number.

This weighted number is then multiplied by the LCS Score.

$$(Ask-Bid/Bid)*LCS$$

My question is if this is a good way to determine liquidity with the limited means I have.
