    Hi All

    I have a curious question about tracking real time market data

    Is there a way to track all the public companies in the exchanges ( more then half a million )?

    To elaborate as to why (if you can track a huge quantity of market data like this) you would ideally be able to jump into trends and high volatility events

    The idea is scalping but on huge huge scale, not to discriminate against any instrument, even penny stocks, as long as the trend is happening to make a profit on the dip/fluctuating price action?

    Get in and out in a short time frame

    Has something like this been done?

    The API/ Python live stream of market data is the first thing that comes to mind but ideally there should be something even better to track multiple exchanges at the same time

    Then the logic will be to program the parameters to detect and notify huge volatility compared to whatever indicators would determine this and jump in the trend half way trough

    This will probably take a mountain of a coder to be able to implement everything

    But would something like this be
    a) potentially profitable in the long term or & short term?
    b) even possible using one or multiple brokers?

    If so what is the best way of going about it (Brokers & language) ?

    If I understood you in a right way, you are going to create something like worldwide screener that would serach for the setups you are interested in, is it so?
    For sure, it seems to be a bit complicated since you will have to recieve and process tons of realtime data. By the way, if you are going to use only scalping strategies, would it be better to focus exclusively on several exchanges with the highest liquidity where such strategies could be applied? Of course, the idea itself is quite interesting. It is something like a dream of any trader - to be able to be present in each situation and to use each opportunity. At the same time you may face several issues while making attempts to bring it to life. For example, you will have to create a system that would be able to calculate the position size in the situation when the price of underlyings should be calculated in different currencies.

    To my mind, it could be interesting to test some arbitration-based strategies or even to try to find corellation between different assets traded on different exchanges (for example, European companies listed both on local exchanges and having their ADR on US exchanges)/
