パブリッシュされたコードCosine distance and cosine similarity
Calculate the cosine distance and similarity between 2 vectors .
The cosine distance is 1-cosine_similarity
and
the cosine similarity is the dot product of two vectors by their magnitudes multiplied.

Can you backtest renko charts ? ☕️

Thanks , MT4 ? Uh-oh . Is it built on live ticks alone or a collection of real ticks ?

:) Do you know the legendary poor quality of MT4 ticks?
I won't be able to answer you but you can imagine that it can't be terrible. On the other hand, here is how I see this mediocre tool: If I'm looking for a profitable strategy or out of simple curiosity I first test on time frames of 15 or 5 minutes. If the strategy works or my curiosity is satisfied I already consider it extraordinary compared to manual trading. Then if the stakes are worth it and the strategy can work in shorter UTs I will probably switch to MT5 or something else. You will therefore conclude that this has never happened to date. The ''RENKO style'' strategy was not a great success. Maybe there are errors on my part or other indicators to add. To have. I no longer have the exact reason for my disappointment with the coding of my strategy in RENKO equivalent but it didn't work like on paper. So whatever the quality of the data, it was not at fault or only partially. I did not have the availability to dig in and better exploit this robot and insist on the RENKO equivalent as a strategy but I will surely come back to it at the beginning of 2024 when I have more availability because on paper it had potential. I will contact you by message for the code.

Besides lucky and unlucky theres easy luck and hard luck .
Let's say you buy a pair , and it goes down (trade 1) VS buying a pair -> it arrives one _Point before your take profit level and then goes down (trade 2). Both those trades hit stop loss .
Now let's say you are optimizing this strategy . The more pointers toward an outcome you leave inside the "virtual environment" for the genetic algorithm the more the genetic algorithm will consider the outcome.I call this making the terrain more "walkable".
So , if you are formulating the reward yourself , and , the reward varies between -1.0 -> +1.0 , are these 2 trades equally bad ? Are they both -1 ? I mean if one day you make pizza and you burn it but the other day you make pizza you taste one piece and its good but your girlfriend steals it from you , breaks up with you and leaves (with the pizza) does that mean you will discard both pizza recipes and start over ?☕️

Great! Also: Unfortunately what you get as a chart has no integrity by itself. Almost meaningless to optimize. Optimization tool is only good to test how much a trading logic depends on parameters' calibration and evaluate its reliability when market atmosphere changes.

you mean the chart comes in with a preselected parameter , the timeframe

here are some numbers from the front page of the popular products for MT5
⚠️The average publication date is 9th December 2022
⚠️78% of products have at least one backtest screenshot
⚠️64% of products have a live signal
⚠️The average duration of the signals is 30 weeks
⚠️The average price is 972 $
⚠️64% of products will increase the price after some sales , or the price is a discount
⚠️Theres almost 61 reviews per product with 202 comments and 3170 demo downloads
⚠️36% is using keywords for ai , neural networks , intelligence gpt etc
⚠️You can get an idea of what the product is from the logo in 8% of cases , and from the title in 19%
Interesting observations :
There's products that have fresh live signals but were not published recently
There's an ea that uses chat gpt (which came out 2023) but showcases a backtest from 2019
There's an ea sporting a funded challenge certificate which links out to a different name than the sellers BUT that name appears to be his/hers employee . The employee also has an mql5.com account and has not posted a review on any of the products . Honorable mention . i got curious 😂😂😂🍻

Also many of the products that have no "FOMO" now did in the past and got to the top . So that number is higher . So the sellers kinda hit the "fair price" the market is willing to pay for their product , stopped the "next price" and are not planning the next scam . i mean the next ai trading algorithm sorry

beautiful activation function curve .
The derivative is the activation value , that will cover any extra calculations that keep the input range from -5 to 5
😍☕️ (ps:don't forget the normalization derivative)

default execution vs open CL + GPU .
OpenCL 5x , and the algorithm is garbage still !
The top of the line GPU out there is 90x faster than the one that did this!
