Hi all,
I start to be interesting in Neural Network, it seems to be possible to do in prorealtime even though it has not Arrays (brace yourself, very long codes are coming).
Now with multi-time-frame support and neural network, looks very interesting for trading.
I found a very useful web that explain neural network in very simple way:
http://neuralnetworksanddeeplearning.com/chap1.html
I will start experimenting with this topic.
For example, I code a Classifier for long entries.

I added TP, SL and a Filter on 5m TF on DJI and I’ve set it going on Demo Fwd Test.
Thank You for sharing @Leo … I look forward to your own Topic on Neurals!

Nope, I moved the discussion to a separate topic, thank you Leo for sharing the code. I subscribe and will follow it with great interest.

Thank you Leo, no offence, but the “problem” with the indicator is that it obviously knows what happened (because it “data mines”) and it loose the information each time it has found a new setup, it doesn’t save it.
How to you plan to take advantages of what the function learned? This is what I think about:
- function is looking back
- function is finding a good setup according to your criteria ( example: ProfitRiskRatio=2 )
- function is starting a new loop in the past starting from the first candle of the good setup found at point 2/
- function is looking for a “similarity”
- similarity is found, increase the score
The “similarity” could be anything from a basic candlestick pattern to an oscillator in oversold territory, for example..
If score > x% then you may have found a valid setup that could be considerate as robust.
I’ll try to code something quickly..

This is a sample code (template) for what I was talking in my previous post:

If it has occurred at least 1 time (during ‘candlesback’) before the beginning of a setup, it scores 1 point. As for the attached picture, the similarity has been found 30% for all the setup (marked with a blue arrow).

Hi Nicolas,
Your code is a very good idea and concept for machine learning using correlations:
The classifier (as I said before is not an indicator) detects a perfect trade and we start to store information and data in that moment ( what you call similarity1, similarity2, similarity3, etc), and study if there is a correlation between the “perfect trade” and the “similarity”
As far as I understand Neuronal Networks, we choose a number of inputs for example rsi[14], adx [20], (close-average[20]), etc, etc, and the variables in the neurons “store” several and many correlations, behaviours, sentiments or whatever you want to call it ( in facts some autors claim that neutonal networks can learn anything if we provide enough data)…. and if that behaviour change… the neural network change and adapt as well!!!
Thats the beauty of Neuronal Networks.
One can imagine that without Array support in ProRealTime is almost impossible…. well, we together can find it out…
I always keep in mind that the financial markets do whatever they want… it doesn’t matter how complex the neuronal network is.
Here is the video that open my mind to the potential of Neural Network in prorealtime
