TDAmerican is one of the worst brokers out there. I used their trading platform. The chart would develop, as time went by, to the right edge of the chart, and then it simply stopped there, no more new data or prices. The new price/data simply disappeared. That is absolutely hilarious. I don't know who designed their chart. But I can tell you this: The person or persons who designed their chart is/are not traders at all. They know nothing, nothing, nothing about trading. As strange as it sounds, most American companies or businesses are run by people who know absolutely nothing about the business. I remember HP computer company was run by a woman by the name of Fiorina who knew absolutely nothing about computers. Or JC penny was run by a man who knew nothing, nothing, nothing about the stuff sold inside a JC penny store. Or USA is run by a man who knows nothing, nothing about managing a country. Hilarious. A trading platform is designed by people who know nothing about trading. IB's chart is not even updated by the transactions. They call it a snapshot of trades. Ridiculous.
