Indicator Reference Page Errors

[DerekMelchin]

Expected Behavior

• There no PHP errors in the docs
• There are no punctuation errors in the docs
• There is an image that visualizes the indicator values
• The Introduction explains what the indicator is and how it's calculated

Actual Behavior

• The indicator reference pages (example) have the following PHP error:

  Warning: include(/tmp/docs/9045b53028ed528cc5895ec5735b784a35d46e54/Resources/qcalgorithm-api/correlation.html): Failed to open stream: No such file or directory in /tmp/docs/9045b53028ed528cc5895ec5735b784a35d46e54/Resources/indicators/using-indicator.php on line 52 Warning: include(): Failed opening '/tmp/docs/9045b53028ed528cc5895ec5735b784a35d46e54/Resources/qcalgorithm-api/correlation.html' for inclusion (include_path='/var/www/beta/core/libraries/Google:/var/www/beta:.:/usr/share/php') in /tmp/docs/9045b53028ed528cc5895ec5735b784a35d46e54/Resources/indicators/using-indicator.php on line 52

• There are punctuation errors in the docs (In this example, there should be no comma after TradeBar.)

  To manually update the indicator, call the Update method with a TradeBar, or QuoteBar.

• This Visualization is not showing the correct image

• This Introduction doesn't define what the Alpha indicator is and how it's calculated, yet the definition is in LEAN.
