In fact, when you're in lower timeframes, you may want to see where highers TF SMA's are without always changing the TF of the chart. This script was created for that.
It's really simply to use, by default only 4 SMA's of the present timeframe are ploted. If you want to check the higher TF SMA's, just tick the lines in the script parameters.
No strategy here, only trying to faster the use of indicators by changing parameters on multiple MA in the same time.
Don't hesitate to leave a comment if you have ideas to improve the script.
