Neural Network CCI - RSI

This is a test of neural network with one layer.
Two layers will follow soon.

Signals are given by CCI or RSI.

Method 1 triggers a change of oscillator (buy if >0)
Method 2 triggers oscillator over 0 (for CCI only)

How to use:
1- launch the strategy on a chart,
2- open "Strategy Tester" tab
3- open startegy option panel
4- modify x11, x12, x13 and x14 to get the best results (net profit, profit factor, drawdown, etc...)
5- repeat once a week

Need help with self-optimization: I couldn't yet found a formula to optimize profit or win% or whatever changing values of x11, x12, x13 and x14 inside the strategy.
