Seems odd that the ATS people think some software is needed for this. I mean, we can all see if price is rising or falling or neither.
I think they use a lot of words to say a simple thing - smart money just means big money and the big money makes price trend: so if you’re smart you’ll follow the trend. The trend is not made by private retail, it is made by the big banks. do what they do, they have the best brains in the business.
