  1. “BHS- my train is the A/C”

    The A/C has 2 big issues.

    The huge one is that the way the system was designed, the C was never supposed to go to Manhattan. You would instead take the local to the next express stop and transfer.
    The local would end at the Court-Schermerhorn station that is now the transit museum.
    The current system is more convenient in that it gives people a one-seat ride into Manhattan, but it causes issues because the C trains have to merge from local to express and then back to local again.
    If these merges did not happen, the A could run even more frequently than the current A and C combined, creating more capacity from Brooklyn to Manhattan.

    A smaller issue is that the C runs 480 foot trains instead of the 600 foot one on most of the other lettered (IND/BMT) lines.

    I am curious – do you have a link to the capacity study?
    Transit is one of my geekiest interests.

  2. Dibs, the exchange uses a form of VAR called Span marginning. The CME developed it twenty years ago to figure out how to calculate margin collateral. And it works like a Value at Risk model and takes into account the value of underlying (the silver) and volatility. Volatility was insane in futures. Our physical precious metals trader (another business division NOT being closed) was telling me about his day managing a position with 6 dollar interday swings.

    I don’t know that the Span program was overridden by the exchange. But it is clear that grandma had no place in that marketplace. The effect of doing what they did is to maintain an orderly market (no defaults) and obviously caused stressed longs to get out.

    Certainly the ETFs have a problem with wholesale redemptions but this in and of itself doesn’t interfere with the functioning of the futures exchange and directly is not a concern of the exchange. They have no stake in market price. Their concern is making sure that they get enough collateral so that nobody defaults.

  3. “dona….have you heard the conspiracy theory around why the margin rates were raised on Silver? Don Cox, who’s a repectable guy, is saying that the ETF was facing a problem if there wasnt a selloff and rather than risk a run on all ETFs because of an issue with one, they orshestrated this”

    dibs,
    I stated that much a few days ago. That they raised the requirements repeatedly to break the small investors using silver as a hedge.
    It won’t work as long as people continue to realize that the debt is unsustainable and the dollar is being devalued into bird cage lining.
    The “big guys” can only do so much though.
    Silver is and has always been used as currency. It’s easily partitioned, transportable, identifiable, it’s rarer than gold and has history on its side.
    I’m always one to debunk conspiracies but this one is obvious.
    Won’t work though unless our economy picks up major steam.

  4. BHS- my train is the A/C- nearly every time I take one of them at or close to Rush Hour I can count on sitting between stations as they back up. The study I read was answering the question of capacity once the AY project was complete.
