  Right full Neural Network now, huge thanks to Leo!

  Tweaks and variations welcome (better exit strategy?).

  Please post full System Code and Performance Stats.

  @stefanb

  You’re off topic…and over optimized 😉

  @grahal

  Thanks for posting it. Now the topic is full of different stuffs. I let you manage the versioning 🙂

  Ha I think it’s a lost cause!?

  I have tried in the past on several Threads to encourage use of version numbers etc, but – whilst we still have folks making elementary faux pas like posting unformatted code (not using the Insert PRT Code button) then I think we have to accept we may never have Configuration Control?

  But I think now this Topic can justifiably be renamed 🙂 …

  Leo posted a later version Neural Network (v1.2) so here is the System based on Leo’s latest self-learning neural algorithm.

  Tested with Spread = 4

  Wow GraHal!

  It looks awesome!

  thanks for testing in an strategy.

  A lot of work ahead! But such a rustic neural network proves than it works, imagine all the possibilities!

  Hi GraHal,

  I posted a little improved version of the neural network… but the inputs totally different.

  In case you feel curious.

  NOTE:

  please add in your codes

  DEFPARAM PreLoadBars = 10000

  1	DEFPARAM PreLoadBars = 10000

  then you give time to the algorithm for learn

  Thanks in advance

  As you know, while I am coding with one hand in the other one my baby is sleeping otherwise she will cry, haha 🙂

  I recall similar scenarios, can be frustrating at the time, but it passes all too quick then the precious moments will be only in your mind also, so enjoy if you can!? 🙂

  Make sure she not swallow a memory stick full of code or she may end up like Nicolas!! 🙂
