Theresa May to make her final speech at 1900 GMT tonight.

Before the vote takes places there is the voting of the amendments. The aim of some of these amended votes is to try and derail the entire vote. The reason an amendment can derail the entire vote is because if any one of the amendments hostile to May's deal passes then it means May loses the vote by default. You can see a list of the amendments here. Here is the list of the amendments tabled. You can also check out the Order Paper here for Parliament tomorrow outlining the order of business for tomorrow.The House of Commons twitter feed and the Labour Whips twitter feed are also worth checking for the list of accepted amendments.

However, if no amendments are voted through then May's Brexit deal will be voted on. . The most popular outcome is for May's deal to be rejected in the first vote. This is based on 40 economists polled by Reuters. However, a re-negotiated deal is my preferred outcome on a second vote at some point in the future. Here is the potential outcomes as outlined by the BBC

It is going to be a volatile day for the pound. Have a look at the key technical areas in play on the daily chart with the 100 and 200 EMA's corresponding to the Weekly R1 and R2 pivot points. They can be used to define and limit risk, especially if one outcome becomes clear quickly.

Remember, if the deal passes then the GBP will rapidly appreciate. Just jump in and take the spike in this instance and save some for the inevitable ride higher. Don't over leverage though, as you never know what twists and turns are in the mix.
