To share an Expert go to Strategy > (Editor tab) and click on the Export button. The program will save the Expert on the cloud and will return a permanent link.
You can copy the link by using the Copy button. When you visit that address EA Studio will open up. EA Studio will automatically load the Expert Advisor in the Strategy page.
Please note that the Expert will be the same as the one you created the link to, but the backtest results could be different. The reason is EA Studio updates the market history data automatically and each time you open the Expert it calculates the backtest based on the most current historical data. This is a great opportunity to perform a test on future and unknown data.
Sharing an Expert is a great way to show the results of your work to others and it can also be useful when you are preparing a portfolio of tested Experts. You can save your Expert links in the browser favorites list or you can make a text file or word document to paste the links there with a comment for the current results and conditions.
