How to buy, install, test and use a MT5 Expert Advisor
Here is a step-by-step guide to purchasing, installing, testing and using Metatrader 5 Expert Advisors in General:
1. First of all make sure you have the necessary funds for the purchase in your MQL5 account, it is always easier to pay with your MQL5 balance, rather than using a credit card during the purchase procedure, or you can use the easiest payment method available based on your country.
2. Find the Expert Advisor you want on the MQL5.com website and go to its product page.
3. Click the Buy or Rent button to continue with your purchase.
4. Choose the payment method and click the green Next button to continue with your payment.
5. After your payment is completed, you will need to open your MT5 terminal in order to download and install your MT5 Expert Advisor.
6. When you open the MT5 terminal, you must ensure that you are logged in to your MQL5 account with the MQL5 account you used when purchasing.
7. Open the MT5 >> Tools >> Options >> Community tab and make sure you are logged in with your MQL5 account login.
8. Then go in the Navigator window and click the Market folder and then Purchases. Then your Purchases window opens on the right with all your purchases and you can click the Install button on the right for the product you've just purchased.
9. After your Expert Advisor is installed you may want to test it. Go and click on MT5 >> View >> Strategy Tester. The Strategy Tester opens below and you need to click on the Expert Advisor selector on the right side of the window first and then from the Market options, you click on the one you've just purchased in order to test it.
10. Then click on the Inputs tab below to adjust the Expert Advisor's settings or load any set file that you've been provided by the seller, in order to test it. Then click the Settings tab and adjust the time period for your test, choose the desired timeframe and click the green Start button on the bottom right side of the Tester window.
11. After you've experimented enough with your Expert Advisor's settings and you've found the correct settings for your strategy, you may want to put it to work. You are now ready to trade on a demo or live account with it. So, open the appropriate chart of the symbol that you want to trade with your Expert Advisor, choose the correct timeframe and then from the left side of your MT5 terminal, in the Navigator window, find your purchased Expert Advisor from within the Market options and drag it onto the chart (or double click it).
12. The Expert Advisor's settings window will open. There you click the Allow modifications of Signals settings and Allow Algo Trading option in the Common tab and click OK.
13. Then you go onto the Inputs tab and adjust your Expert Advisor's settings or Load any set file, you've been provided by the seller, by clicking the Load button in the bottom. After you've finished adjusting or loading your settings, click the OK button.
14. After you've closed the Expert Advisor's window, you will see that there is a red sign on the top right of your chart. That means that your EA does not trade yet. You need to click the Auto Trading button and instantly the sign will turn green. Now your Expert Advisor trades on your demo or live account.
