Convert a mq4 regression indicator to mq5 include current buffered angle readout

Convert a current indicator from mq4 to Mq5 using any regression indicator freely available if current one does not convert easy. (I will provide current program and new regression source code if needed). It measures how many bars with a common regression indicator and calculates a buffered angle to 2 digits on the close of each current bar.Include the number of bars settable on the indicator. Viewing lines can be turned on or off as Std, dependant on choice.
