@tcanuto Check my Tutorial EA. I use some boolean flags as well as switch ON/OFF blocks in there.
One example is the CoF feature. On the init tab I read the values from the constants and set bool flags accordingly

The on the on Tick tab I check the flag.

Of course this example is for generally switch on/off parts of the code by EA parameters. But it may give you an idea.
I like the bool flags. However, you might use the numeric (if more than 1 option) or string (never used) type as well.
