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.
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.
