Convert MT4 indicator to MT4 Expert Advisor

EXAMPLE [SP500]H1.JPG:

Arrows code 5: Label LIME / RED:

mark the entry and exit points of each trage (the indicator is MTF and Redisign The standard setting is H4 - JPG is H1)

At the same time the LABEL figure sets the STOP LOS.

The entry point of each trade is obviously not the same as the LABEL figure but has a few pips difference - SEE PIPS.JPG

SHORT: entry point 3838.15 with fixed LOS STOP at 3852.23 (as per RED LABEL)

As a further option (variable) we could add PIPS to the LOS STOP, for example in this case +500, then the LOS STOP would be 3852.23+5= 3857.23

If the trend should change in the opposite direction, in this case LONG, the open short position is automatically closed and a LONG position is opened with the same principles.

My questions are:

Can you do that? turn this indicator into EA with these variables and constants?

If yes: 

-what are the costs?

-what happens with copyrights in case you want to commercialize this EA?

Thanks!
