Smart Opener

Hello Developers,

I need a utility that allows me to open order quickly. Something similar to the image bellow.

If choose Buy AUD and sell NZD and GBP, then I expect the position of AUDNZD in BUY and GBPAUD in SELL, each has it's own lot size as well (this will be an input). Another input I would like risk to reward ratio. So when the position is opened, if my balance decreased to 2% the close the position and vice versa when it comes to the reward. I also want to check the spread, if the spread is to high, then do not open trades ( how high the spread will be is adjustable).

Thank you
