I can do a scan and find stocks with weekly options, there are about 600. How do I find ones that are in a trading range (i.e. price is moving sideways) over the last 3 months? Not too fussy about this and ready to try any ideas. They need to be in a narrow band of movement horizontally. Not sure if this can be done with one or more studies or if it needs some thinkscript code. TIA
