Long/Short Idea on AVIVA LSE

I am new to trading so don't take me for granted.
Due to the recent fall of Aviva, it may be worth investing in.

Using previous points of support and resistance there are two ways in which the market will go.

The shorter one will be a rise up to a previous level of resistance.

The longer one may be a shorting opportunity after which you can go long and make further profits.

I am betting on a early swing in the direction oppose to the later one, just because of the fact that a more previous support was in place.

But the latter one will be more overall profitable as you will be able to short now and go long later which may lead to large profits.

I have proberly made some mistakes feel free to comment on them and i will take any CONSTRUCTIVE critisism and enhance my skills upon it.

Many Thanks.
