Concerns regarding the use of our Expert Advisors prepared for MetaTrader5 are detailed on the mql5.com website, the MetaTrader5 application development platform. The rules there apply. In short, there is no contract or mandatory minimum commitment for any expert advisor. You can use the trial period if you prefer, or if you don't like it, you can get your payment back within 7 days of purchase. Alternatively, you can purchase full usage rights for life, activate them in 10 trading accounts registered in your name, and use them seamlessly. You will benefit from free updates. We strongly recommend that you try them on a demo account before purchasing, adjusting the settings according to your risk appetite, and then use them on a live account. You can ask any questions you may have by emailing us through our website."
