On MetaTrader 4, click on the "Tools" menu and choose "History Center". In the menu on the left-hand side, double-click on "Fx Majors/Fx Minors" and then double-click the currency pair of your choice and the time frame. To view the quote history of this pair, click "Download".
If you want to add an Expert Advisor in MetaTrader 4, you must save it to the MT4 directory on your PC. Click on the Windows "Start" menu, select "My Computer" and open the "Experts" directory: "C:" > "Program Files" > "ToTradeFx MT4" > "Experts". Then, drag the Expert Advisor file to the "Experts" folder, restart MT4 and you should see the "Expert Advisor" folder in the "Navigator" window. Now you just have to drag the Expert Advisor to the chart of the pair you want it to trade.
First you must ensure that trading is permitted on the Expert Advisor. To check this, go to "Tools" > "Options" > "Expert Advisors" and make sure that the "Allow Live Trading" feature has been switched on. Then, look at the "Expert Advisors" button in the tool bar on top to see if it is green. If activation has been successful, there will be a smiley face at the top right corner of your chart. If you are still experiencing problems, check for any errors in the log files in the "Experts" tab (this is located at the bottom of MT4, in the "Terminal" window). If you still cannot track the problem, please contact our Client Support Team.
