I'm using it, continuously.
In my opinion, everybody here is right:

- they don't do anything that you couldn't do yourself, even the best ones
- they do save you time, especially if you're into scalping and trading multiple assets at the same time
- they will lose you money very quickly if not programmed correctly
- and it is good sometimes that they can't be shaken by emotions or adrenaline rush.

My reason for using it along with my manual trading is that I like coding in general and I do everything myself, so I get my daily dose of excitement with every small achievement. I don't make any losses, well past that lesson using 'paper' trading account.

You still need to adjust a lot of settings, do your testing, re-adjust settings accordingly and so on; plus to code and implement your own buy/sell signal since it is an expensive exercise testing paid signals to find what might work and which ones to stay away from. If 'paper' trading option isn't available to carry out testing, then you're destined to fail, regardless.
Not to mention the time and effort required just to get it going.

Each to their own, but it definitely isn't something that will work out of the box and make profit - we'd all die of starvation if it did - because nobody would be producing anything any more but rather be trading, having heaps of money but nothing to buy with it!

That's my 5 cents.
