I feel like no tool is there to make you money, there is no way that just because you downloaded some tools you could be great at trading, or using any tools would mean profiting in trading. Obviously speaking they would "help" you, that way you wouldn't really be blind when trading and it matters but that is just one thing that could help you but when you get help from the tools it would make it easier.
So, when you are trading, you have to realize that you are either profiting thanks to your own knowledge, or you are losing money, the tools you are losing would mean absolutely zero when you are not a smart trader, it wouldn't really help you out the way you think it would help you out. So all in all I would say it is not as vital as people think it is.
Tools are already there and it depends on how a certain trader would do make use of it and since we do have different level of intelligence and experience then outcomes or results would really be different to each other.
For news aggregator or even to those exchange price differentiation or comparative then its useful and its one of the tools but it doesnt mean that you would really be making money or guaranteed results.
Nothing is enough when you dont make profits or money.Consider its working if you do already some greens or gains. Just continue the work and learn further because market is always
been unpredictable where you do need changes depending on the current market condition.
