  <p>fre‌qtrade hyper‌opt --stra‌tegy GodS‌traNew ...‌</p>
  </li>
  <li><p>It will run GodStraNew.py file as therdparty app</p>
  </li>
  <li><p>I'm now inside GodStraNew.py</p>
  </li>
  <li><p>I will stop the code after seeing this varia‌ble:</p>
  <p>dnaSi‌ze=‌10</p>
  </li>
  <li><p>Now will edit the GodStraNew.py file As which I want,
  for example, adding 9 lines to it.</p>
  </li>
  <li><p>than run again the hyperopt command with args, and without exiting!</p>
