Failing to change MA types in OSMA

Hello, I`ve tried playing around with the code of the OSMA.mq4 in order to change the moving average types but failed.

What I need is an indicator, which would allow me to see :
The distance between the SMA and LWMA
Which would basically be an OSMA I guess.
The problem im facing is that the moment i apply the indicator to the chart it gets removed.

My settings are the following 30,30,1

Im basically trying to get rid of the SIGNAL LINE because for 1) I don`t need it, and for 2)Because of me setting it to 1 the indicator gets removed automatically by mt4

You need a modified MACD.

Thanks allot ! Wonderful) Exactly what I needed
