What is the market?
One person described it as random movement within predictable boundaries.
If this is true...
and you are trading the random part, you might have random wins and losses.
You might attribute those to whatever indicator or concept of trading or mathematical formula you are using at the moment. But would you ever become consistent?
Statistical probabilities do not apply to random movement.
The predictable boundaries are described in any number of ways. Elliot wave theory, auction market theory, countless indicators. I like the simplicity of AMT, and that is my focus. If you have questions about predictable boundaries, just look at Db's posts over the last week. Boundaries called in advance. I am choosing to be a trader in that way.
'Traders probability' has to do with anticipation in the AMT sense (at least in the way I'm thinking about it), and how you manage a trade. At this time I don't need or even want to know statistically what the market will do at a predictable boundary. I trade mechanically at those times and places and pay attention in a pretty much mechanical way. I like it.
Still dont understand you Hooti. I am gonna write it as I see it.
People who trade without a plan, have to rely on VaR, they buy or sell at any given level (no matter what) and think that they have a x% probability or not being negative in more than X ammount of dollars in a defined number of days or seconds or minutes. That VaR is calculated with the periodic volatility of the asset and is intended to reflect how wide moves are.
When you trade with a plan, the objective of the plan is to move the odds in your favor, as entering on a extreme, and not only on a extreme, but on a REV or a RET after a REV once the previous trend is proved to be over (the stride is broken or the line is gone). Or to enter on a RET after a BO, once buyers or sellers have been rejected off a previous value area.
Now, that doesnt mean that there is no probability there, as your plan will end up telling you what is the probability of a scratch being hit depending on how the rest of the parameters are set. That is the probability of failure of your entries. Once you get that number, and you consider you have a significant number of observations (Guess there is no consensus there) that will provide you with confidence. If your stats say that you have a 50% chance of getting scratched on any given day, and you make 10 trades a day, then you expect at least 5 scratches to occur, and if they occur you wont freak out. If you get confident enough not to freak out, then you will trade more relaxed and your brain will be able to focus longer.
I am not sure if that is what Db refers to as Trader´s probability, perhaps not. But that is the way I see it, as always in the market, perhaps I am wrong and I will have to scratch
