I will code a custom trading robot, ea for mt4 or mt5

You just need to have a clear trading plan with clear trading rules and send me your explanations in Word, PDF, or ask me for my "requirements form" and simply fill the requirements form with your trading rules.

Yes, It is possible to create multiple assets EA, for example, make it analyze the VIX to trade on SP500.

Yes, many traders choose to work with EAs that will analyze higher time frames, like D1, W1, as a screening level before analyzing smaller timeframes, like M1, M5, H1, etc... this 2 levels of screening can use completely independent indicators.

Yes, as long as you can send me the mq4 or mq5 file with the Indicator, it can use any indicator you already have, on my Premium Gig or Custom offers. Do not purchase my Gigs right away, when you are working with Custom indicators, I need to see the files in advance for feasibility study.

After you receive your EA, and test it, if you find out that the EA is not doing exactly what was in the requirements, I will adjust it free of charge for you. Upgrades and new requirements are charged as a new modification job. There is no profits guarantee, there is no satisfaction guarantee.

Because I am already doing EA programming for many years and I already have many of my own coding libraries, as well as frameworks.
