Decision-making error - page 6

 
George Merts:

That's exactly what I mean - the order is a tenfold difference. Let's estimate how much more accurate my prediction will be.

Assuming the Eurodollar has a normal daily range of 100 pips, the average error of my "forecast" based on the MA would be 50 pips. Your "random" forecast is a forecast in the 7K pips range. The average error is 3.5K pips - roughly speaking, an order and a half. But that is on the daily chart. And if we take the minutes (let's not talk about ticks), which the local super traders terribly like to trade on, we obtain an error of about the same three orders of magnitude.

The price movement is not strictly determined, of course. However, it is not random at all. Several times I've conducted an experiment - we take any MQL-examples EA, generate a random sequence of bars, find approximately the same sequence of bars on the history and optimize the EA so that it shows a good profit on the history. And we run the same Expert Advisor on similar random bars - and at best, the profit disappears. Usually losses are incurred.

In my opinion, this is sufficient proof that the price movement is not random.

But if you think I'm wrong... well... Maybe I am.

You're wrong. There is no 7,000 points in the forecast. There is a variance of about the same magnitude as in the market.
All in all, it is too difficult to explain the basics of statistics.

It's not about the TS, it's about! asking why there is a fear of opening a trade with your TS, and it's a psychological issue.
You just have to learn to trust yourself. And change your mind every five minutes ...Imagine you have a friend and he changes his mind every five minutes ...The question is what happens next in your relationship?

In general, it is too difficult to explain the basics of statistics.

Strangely enough, I have no problem explaining "the basics of statistics". Probably because I don't know them...

But, understandably, it turns out that there is already "a variance", which means that you can't say that the price is "independent". Just the existence of this very variance and its use in the forecast proves that there is a pattern in price movement. A forecast that is within "three sigma" will be far more accurate than a forecast that is evenly distributed across the entire range of values.

And you say "random"... Of course, randomness is present, but it is present in absolutely any phenomenon, and it does not prevent its prediction, even if with errors.

Right. So, in order to "trust yourself" - you have to have a perfectly clear, history-tested TS.

Don't tell me, I don't have any brains at all, I don't know what to do with your lofty thoughts that you couldn't even formulate... First stating that "past prices are in no way related to current prices", and then suddenly remembering "the basics of statistics", you might even remember the correlation... Certainly, I am as far from such "intellectual heights" as the moon...

You don't have to tell me, I don't have any brains at all, how can I be bothered with your lofty thoughts that you couldn't even formulate... First, stating that "the previous prices are in no way connected with the current prices", and then, all of a sudden, you remember "the basics of statistics", you might even remember the correlation... I certainly do not have such "intellectual heights" like the moon...

What can I articulate when you blatantly state your ignorance of statistics and then erroneously (which is natural) calculate a difference of several orders of magnitude between predictions? If you don't know, why are you trying to argue on these topics and then also taking offense at my, as you think, snobbery?

I can forgive myself, I do not know statistics. I can only ask you what is the right way to do it. Enlighten me, unintelligent, how do you calculate the difference between the forecasts?
