Isn't there some python script out there that will read a twitter feed , write to a text file so that MT4 can execute the trade. One could trade in real-time for many people like this.
Of course you need to define what slippage is still acceptable to run the trade (i mean the price movement due to delay) and what lot size would be.
Than you just need to select well performing Twitter traders and big portion of luck
How much would you pay to programmer to get it done?
I like what I trade, I trade what I like
