Here is another version of my Flex Renko script. It is uses percentage-based brick sizes to draw the Renkos instead of ATR or static brick sizes. What makes the percentage-based drawing style great is that one doesn't need to adjust stops so many times like they would with a ATR based Renko. It also makes moving between tickers smooth as well as one doesn't have to adjust the brick-size for each name.
to use: By default the setting is ".001" or 10 basis points. So ".01" is 1 percent or 100 basis points and so-forth. This style is perfect for those traders who make trades on a percentage basis over a price-level basis. It's also good for percentage-based stops.
The yellow lines represent where the price needs to go to draw another Renko brick.
