Build an EA that gets data in JSON in real time

I have a signal provider and I'm currently building an API that will generate trading signals using the HTTP protocol.

I'm looking for an EA developer to build a robot that will read these signals using the MQL5's rest API function and execute the trades with a given risk amount. The data will be in JSON format, so it should listen to

GET "http://myapp.com/open/{symbol}"

to get :

{

  symbol: "PETR4",

  direction: "buy",

  stopLoss: 21.04,

  takeProfit: 22.00,

  priceLimit: 21.5,

  timestamp: 999999999,

  executed: false    

}

where "symbol" is the current symbol, "priceLimit" is the maximum price that keeps signal valid for "buy" trades, or the minimum price that keeps the signal valid for trades in "sell" direction. After opening a trade, the robot will call

POST "http://myapp.com/open/{symbol}" { executed: true }

to update the signal, and then listen for the close signal:

GET "http://myappcom/close/{symbol}".

I will provide a demo account so you can test it. NOTE: It's not an FX robot, it's for the Brazilian stocks market. The robot should be compatible with MT5.
