We know and can read the news, and we can predict the price of currency. So I guess we'd better monitor the price. After all, if we are a professional trader, we do not have to worry about losses anymore. Because we already know when to buy and when to sell.
It's true, trading bot is no a silver bullet especially in long term.
But bot can help in short term. For example, each day we have some fluctuations of the rate(even on a sunny day, without good or bad news). Its almost impossible to predict this fluctuations. But for bot it is possible to analyze number of orders in stock, capitalization, number of new orders per hour etc and compare it with historical data(find similar situations in the past).
From my point of view: with good bot it should be possible to win 0.5% each 12 hour with minimal risk.
And I think it's batter than win 3% a day but with HUGE risk to loose more.
I started to implement my own bot, but who knows if I am able to finish it
