Quote from Trader13:
The point made here prompts a question: Are traders in this forum most successful using ACD to make directional trades, or volatility trades? I see references to a "long bias" or "short bias", and I'm not clear if this refers to a uni-directional trade (pure long or short), or a spread trade that leans long or short but benefits from volatile price movement in either direction?

I think the latter part of the question would be directed to Maverick. He made a comment a few weeks ago about a spread trade being long volatility. To be honest I never thought of it that way. I always think of options etc. when I think of vol. Maybe he can expand on why spreading not Coke vs Pepsi, but using "outside the box" pairs is a vol trade.
Quote from Maverick74:
Spread trades are not long vol, they are exploiting a relationship between two products. Spread trades can be long vol or short vol in nature. Mean reversion traders have a payoff structure that resembles a short vol trader. Mean diversion traders have a payoff structure that resembles a long vol trader. Spreading Coke and Pepsi is a mean reversion trade.
There is no "outside the box" pair. You are either betting on convergence or divergence.
I missed this post from last week which suggests that traditional modeling and backtesting is an exercise in futility. Another profound insight worthy of reflection.Quote from Maverick74:
... I want to find stuff you can't back test for!!!!!! That is where ACD comes in. Anything that shows up on a backtest for you will show up at every quant trading desk in the country. I want to find the moves "before" they happen.

Quote from Maverick74:
I think I told this story before on this thread. Back in the day when I was an active equity daytrader, I was at this firm in NY and I was talking to another trader. We would share notes and ideas everyday on what to watch and so on. I would always pull up these stocks that had big moves the previous day and would say, I'm going to watch this today. And this guy would say why, the move already happened, it's over.
Then he would show me the stuff he was going to watch and I would say, why are you watching that, that thing doesn't move? And he would say, that's the point, it hasn't moved yet, I'm anticipating it moving today. And I would look at the chart and ask him how the hell did does he know that. And he said, I don't, you just have to put the pieces together.
I really think this is what 95% of the guys on here don't get. You can't trade the obvious. You can't trade yesterday's move, today. At some point, you are going to have to get in first or early and anticipate something happening. And that takes a lot of work. No shortcuts.
