    Hello, my name is Anatoliy Schneider. I'm a programmer with 10 years experience, including more than 6 years of experience in MQL language. I've created a wide range of EAs (Expert advisers), indicators and scripts for both individuals and small companies. My main interest is in developing complex expert advisers and custom indicators from the customer's description of the algorithm and supporting these projects in the future, improving them even further. Before we engage in any business relations, I would like to explain in detail the way I work. For every project I estimate how many hours it will take me to develop, then provide a quote based on that estimate. Please note, that I cannot provide an adequate quote before I know exactly what I will have to do. After I quote for the project, I must deliver 100% for the price I ask, and if I do not know what exactly I will be doing, I can only roughly estimate. Therefore, we must discuss all necessary development and features before I accept the project on Freelancer.com. All additional functions above what we agree upon will be quoted separately. When I accept the project, I require 100% milestone (but NO upfront payment) before I start working on it. I am sure that any serious buyer will understand this precaution. Being also a Forex trader with 7 years experience, I can consult the customer in market specific questions as well as platform (MT4) related information, help testing the EA or manual trading system and modify existing EA. This service is available at the base rate of $50 per hour. If I am required to work with any code that was written by another programmer (existing EA/indicator modification), the overall cost for the project will be higher (compared to the same changes made in the EA I originally written). This is necessary in order to cover up the time I will have to spend analyzing the code and making sure that every function is working correctly in it. Please understand, that after I start working with the code you provide me, I will become responsible for it, and therefore will have to fix any mistakes that the other programmer might have made. If you have any questions, please feel free to send me a PMB message. Thank you for considering working with me. Anatoliy Schneider.
