Expert issues / compiling errors

Hi,

my expert does not work any more. 

It uses the below indicators:

Color Candles cross MA - https://www.mql5.com/de/market/product/1255?source=Site+Market+MT5+Indicator+Search+Rating004%3acolor+candles+cross

HMA Color with Alerts MT5 - https://www.mql5.com/de/market/product/27341?source=Site+Market+MT5+Indicator+Search+Rating004%3ahma

In metatrade journal I see the following notification: 

version of 'Color Candles cross MA.ex5' is obsolete, recompile it

In metatrader editor I see the following after compile:

cannot convert 0 to enum 'ENUM_TRADE_REQUEST_ACTIONS'

cannot convert 0 to enum 'ENUM_TRADE_REQUEST_ACTIONS'
