Closing line value - approx. Half of value when placing bet?

Hello,

Would be interesting to know if others also experience that approx. Half the value at placement goes away until the closing line? (I use max 12h to start)

For me this seems to be pretty consitent pattern.

I recently wrote an article about this:

Hi,

Regarding this article, so are the value percentages shown not adjusted for bookmaker margins? So if I placed a bet at 2% value the actual value when adjusted for margins might be negative?

No the value is always adjusting for bookmaker margins.

But the margins are changing all the way up to match start (clv).
