One of my favorite indi is LWMA 55. I dont know why but the price seems to react a lot of this line. People say that MA is a lagging indicator and I agree with them 100% but do not use MA as a signal generator, instead use them as a dynamic support and resistance.
For those of you who love to experiment, try putting LWMA 55 on a chart and see how price actually interact with the line. Its not magic but its a mathematical calculation.
Dont get me wrong, you may not be able to trade using MA 55 alone. Try putting LWMA 13 in there as well and remember they are not signal generators. Treat them as dynamic support and resistance.
