<p>A new user asked this question:</p>

<p><a href="https://stats.stackexchange.com/q/344110/58675">Neural Network for Foreign Exchange Prediction</a></p>

<p>In my opinion it's quite good as a first question, but it's hard to answer. I'd like the help the OP improve it. However, I'm not sure how. The main problem IMO is that we can't say why her/his code doesn't obtain the same results as the book's code, because we don't have access to the book code. I was thinking to suggest two improvements:</p>

<ol>
<li>Modify the question in "did I make any errors in my implementation of this NN for Foreign Exchange prediction?" and add code, interspersed with text so that the post doesn't become an unreadable wall of code</li>
<li>Add a link to the data, and some plots</li>
</ol>

<p>However, at this point it seems to me that the question will become more on-topic on Stack Overflow than here. So I thought to suggest splitting the question in two questions: one, on topic here, where the OP describes the model more in detail, plots the data, etc. and asks if s/he is making shuts mistakes in the model definition.
Another, on topic on SO, where the OP shows the actual implementation of the model. It's a lot of work for a beginner, but I don't have other ideas. Directly posting the code to SO doesn't seem right: I'm now due that talking about Hampel filters, AR coefficients, etc would make the question on topic there.</p>

<p>What do you think?</p>
