Let stock A traded at 109/111, let's assume I want to simultaneously buy and
sell stock A and
recorded buy at the best ask
and sell at the best bid, the
resulting portfolio will
incur a loss due to the spread. (i.e. buy at 111 and sell at 109 therefore loss of 2).
But it is more realistic that since I bought at 111 then the latest traded price will be 111 ...

I am actually getting a slightly different convexity adjustment to Antoine's:
For clarity of notation, I use: $T_s=T_1$, $T_e=T_2$ and $yearfrac(T_1,T_2)=\tau$.
We then have (by definition of Radon-Nikodym derivative):
$$\mathbb{E}^{Q_{T_1}}_{t_0}\left[L(T_1, T_1, T_2)\right]=\mathbb{E}^{Q_{T_2}}_{t_0}\left[\frac{\partial Q_{T_1}}{\partial Q_{T_2}}L(T_1, T_1,...

I think that your question can be solved easier. You may ask me why. Here is my answer:
First of all the LIBOR forward rate $L(t, t, T)$ is $\mathbb{Q}^{T}$-martingale, where $\mathbb{Q}^{T}$ is a $T-$forward measure defined with the following Ranon-Nikidym derivative structure:
\begin{equation}
\displaystyle\frac{d\mathbb{Q}^T}{d\mathbb{P}} = \frac{e^{-\...
