cAlgo Robot required developed from Indicators

I am a private individual looking to have a robot developed for me that will place an order based on a combination of indicator signals. Similarly, the order is to be closed out based on a crossover of indicators. Only one order can be alive at one time per currency pair, but I want to be able to run the robot in many currency pairs simultaneously, and to be able to modify the parameters of the robot for different currency pairs.

I have traded manually before, but am completely new to robots.

Can anyone help me please? I can provide more details.
