neural network versus indicator

[GizmoM]

Hello,

sorry if the question has already been asked in a different way because I did not find it.

1/I am starting to get interested in automatic trading but I am wondering what seems to be the best or rather the difference.

There are all the indicators that we can develop from macd, moving average, bullish ... and decide from our feeling and technical documentation to apply a rule to buy or sell.

and 

on the other hand I think of the recurrent neural networks that will take the history and try to predict the next move to trigger or not buying / selling.

2/on a neural network is useful / interesting to include algos:

- bank scalper

-bull versus bear

...

because it distorts the neural analysis

thanks
