This script will show lines of support/resistance in each period you set (default is 1week). It shows 6 levels with the difference you can set too (default is 5%). The reason why I set default as 5% because as I notice the market will get bounced when it reach 5% up/down and hold that level for some time before it start moving up/down again. Hope this script will help you decide whether it's time to buy/sell when it reached the levels. Thank you.
