Gentlemen!
So what shall we feed to the input of the neural network? What error function shall we select?
Judging by the content, not many people are interested. Many people think it's about the software....
I suggest you start with the slope of the regression line with different periods. And you can start with different TFs. :)
Functionality of the error - maximum profit.

Yeah, there's a lot of neuronics threads going on. And all over the place the flooders clog any discussion with stupid requests for software and dozens of messages "me and me and me".
So there's nowhere to discuss it properly. Maybe there's a strictly moderated forum where they shoot the flunkies? If you say one word, you get a reprimand; if you say two things off-topic, you're ignored forever.
Cloth, you got a lot of places to hang out, maybe you have a place in mind?

Oh man!!!, so many topics about neuronics. And all over the place the flooders clog any discussion with stupid requests for software and dozens of messages "me and me and me".

Cloth, you got a lot of places to hang out, maybe you've got a place you'd like to try.
I've started a forum. I'm going to graze there now :) And I'm inviting everyone to have a practical discussion. I'm going to shoot down the flooders myself. :)

I'm transferring my findings from different places there little by little.
An example of a simple non-network
MICROSOFT VISUAL C++ 6.0
network learn XOR operation
Another simple network !
MICROSOFT VISUAL C++ 6.0
this version allows you to add layers - change the number of neurons in layers
initially there are 3 layers in the source
2 neurons at the input - two in a hidden layer and one at the output!
// Create a 3-layer neural net to solve the XOR problem, with 2 nodes in the first two layers,
// and a single node in the output layer.
CBPNet XOR( 3 /* num layers */, 2 /* inputs */,2 /* hidden */,1 /* outputs */ );
// connect the neurons up
//
// O - Output
// // \
// // O O - Hidden
// ||
// | | X
// |/ \|
// O - Input
//
for example if you put 3 neurons in a hidden layer, the result becomes more accurate
CBPNet XOR( 3 /* num layers */, 2 /* inputs */,3 /* hidden */,1 /* outputs */ );
increasing the number of layers also requires increasing the number of neurons in the hidden layers
CBPNet XOR( 4 /* num layers */, 2 /* inputs */,20 /* hidden 1 */ ,5 /* hidden 2 */ ,1 /* outputs */ );
when increasing the layers you also need to add a call
// apply the bias to the hidden layer, and output layer
XOR.SetBias( POINT2D(0,1),BIAS_GLOBAL );
XOR.SetBias( POINT2D(1,1),BIAS_GLOBAL );
XOR.SetBias( POINT2D(1,1),BIAS_GLOBAL );
XOR.SetBias( POINT2D(0,2),BIAS_GLOBAL );
I managed to get the result, but network is much slower to learn!

and an absolutely beautiful tutorial!
It works beautifully. You could also try teaching the network a multiplication table, in the form of pattern recognition.
Like: in[0]=2; in[1]=2; out_des[0]=4; etc.....

Functional error - maximum profit.
Maybe it would be better to use Error Function ality - not maximum profit, but unlinkage (difference between forecast and Close[0]).
