I already have an Expert Advisor, but I need a new tool. My EA works as follows, he is an arbitrator. Consequently it uses a platform as a data server and a second platform for trading. In my tests I have obtained good results as you can see in the annexes. But the real account, the conversation is different for obvious reasons. What I need is the following: MT4 Data Server Account 125ms (I already have) MT4 Demo Account Trade 240: 260ms (I already have) MT4 Real Trade Account 230: 260ms (I already have) I need a tool to send the prices of MT4 Demo for Real MT4 with maximum 3.5ms delay, it is like a bridge. For what? For the EA log in Trade Account negotiate it as if you were trading in the Demo Account, and thereby obtain similar results to the Demo Account.

Hi there! My name is Matt Graham and I’m an entrepreneur starting a local service business. The project we are currently working on is getting our website up and running. It will be using a WordPress theme so first I need someone to install the theme with our hosting. Then we will be making a few cosmetic changes along with installing a few pop ups, chat functionality, etc. We will also need to install a Google Analytics pixel and some API's for payment or Social Media so it's a plus if you have this experience as well. Basically looking for a well rounded developer to grow with us as we work toward building more complex site functions. If you are a good fit, there is room to grow in the position as we expand to other geographic locations and our operations grow. I’m looking for someone detail-oriented, reliable and positive. Big bonus if you consider yourself an optimist. Applications without the following will not be considered. Please let me know: 1. Your hourly rate 2. What hours you’re available (please convert this to the US MST time-zone) 3. Your experience with WP websites with links to past work Big thanks! -- Matt

I have an API designed and need to chat with an expert on API best practices to find any potential flaws. Assume this to be about an hour of skype call. The problem is that this is really urgent and needs to happen today. Within the next couple hours. Thank you. PS: Don't waste time on the cover letter. Write a sentence on how you're capable of doing this. I'll go through your profile anyway.
