I wrote this script just to trade BTC . I prefer daily and weekly charts with this script but lower time frames are also preferable.
Since some of the lengths are too high; older exchanges are recommended due to their relatively deep historical data.
While MA1 is for taking actions like 'take profit' or 'stop loss' or just to follow 'price action' easily, other MAs are for seeing supports and resistances.
MA6 and MA7 are disabled by default in order to minimize the confusion but you can enable them from settings if you need to.
Since some newer exchanges have less historical data, you may not see MA4 and MA5 on the . In such circumstances MA6 and MA7 might be helpful to use as substitution. Some may like to use all of them.
I am using this script just for BTC but it can be useful for other coins as well.
