Earlier today the GoldGerb asked me how to put together a scatter plot for raw edge discovery as introduced to you by Scott during my Tenerife adventure. Since my gums and I are feeling a bit better than anticipated I thought I may as well condense some of the exchanges I’ve had with him into a dedicated post. It is my belief that raw edge discovery (or RED as it shall be known henceforth) is an integral but much neglected aspect of system development.
I keep getting distracted, but I’d like to move ahead quite rapidly now since Mole will be back on deck soon enough. Today’s post has enough information for you to go ahead and build working mean reversion trading systems right now, with not that much work involved.
I think we’ve covered in enough detail the idea that the best systems are based around a simple and clearly articulated idea, which can be tested for veracity.
The problem with complicated ideas is that our brains are built to believe all kinds of bullshit that isn’t true. Look at the recent election for a perfect example, we are a walking stew of cognitive biases that fuck with us [...]
One continual theme in my own trading is that every time I think I have it figured out – I get punched in the face with a unexpected problem. The tendency is to go more complicated, but often the solution is a degree of acceptance around the nature of the game. Sometimes my edges work, sometimes they don’t. Sometimes they stop working for long periods, 6 months or more. That’s actually ok for me, but it’s not ok for other people. The ultimate systems you choose have to suit your personality. If you cannot handle extended periods of working hard without making money (I can) then you have to retool your systems to avoid this.
The textbooks would have us believe that markets are smooth and orderly. We have a nice downtrend and then when it ends we have a nice uptrend. In theory all we have to do is wait for the right time, buy, profit.
Reality is messy and choppy, and most of the time we are unsure if the old trend is in play, if we have transitioned into a trading range, or are trying to reverse. Each new bar of price action gives us critical information, until we can rule out each of these options. Eventually we get betting odds, and we bet.
Today I’d like to explore the tell tale signs that a new move has the potential to become a trend, and not just a counter trend [...]
