AFL for extracting End of Week and Buy / Sell basics

#1
Respected members,

1. I wana make AFL exploration for extraction of weekly HL range ( of last 10 weeks ). Then i will use excel to get average of these 10 HL value that i can later use for targeting price levels.

2. I would like to request for a buy / sell on Weekly MACD. But in MACD i want to mention 20, 35, 12 ( instead of 12,26,9 which is default )

3. I would like to extract weekly RSI and STS as well.

You guys are extremely helpful and i am glad i get this forum.
Appreciated !
