# Colored Volume Bars [LazyBear]

Edgar Kraut proposed this simple colored volume bars strategy for swing trading.

This is how the colors are determined:
- If today’s closing price and volume are greater than 'n' days ago, color today’s volume bar green.
- If today’s closing price is greater than 'n' days ago but volume is not, color today’s volume bar blue.
- Similarly, if today’s closing price and volume is less than 'n' days ago, color today’s volume bar orange.
- If today’s closing price is less than 'n' days ago but volume is not, color today’s volume bar red.

Buy the green or blue volume bars, use a 1% trailing stop, and stand aside on red or orange bars.

As you see, this is more for entry confirmation. I have not tested this on any instrument.

You may have to tune the lookback period for your instrument. Default is 10.
