Call / Put functions from MQL language to place BO trades to brokers web platforms

Hi,

I would like to write a MQL function PlaceOrderBO(string symbol, int direction, int expiry, int investment)

where symbol is the name of the asset, direction is OP_BUY o OP_SELL to indicate CALL or PUT order, expiry is the expiration time in seconds of binary option, amount is the quantity of money placed in the trade.

The execution of the function should place a trade to a binary option broker using a web platform. 

The function will return True if the trade was placed properly in the broker platform, False if it failed.

In normal conditions the placement of the trade should not take more than 1 second. 

In normal conditions the fault tolerance of the system developed should be no more than 2%. 

The supported brokers should be at least : 24Option and StockPair.

We might interface with other brokers in the future.

I am aware that MQL only might not be sufficient to develop such a function.

So please let me know which technology (Json, Jquery, Web emulation, etc..) do you intend to use to achieve goals of the project. 

Please give me your best offer and tell me about your experience if you already designed similar systems.

Regards. Renaud.
