Thanks to Esperio technical support for their high-quality work and help. I am beginner in trading. I opened an account with Esperio because this company was recommended to me as reliable and proven. Since I have no experience working in a trading terminal, I inadvertently did something and could not load the charts. It was awkward to ask for help from a friend who recommended this company to me, so I wrote to online technical support consultant and I was told me in detail and step by step what to do and how to get everything back to how it was before. I was worried a lot, but everything worked out with their help. Once again, many thanks to them for their help.
