SPY Key Levels

Use Case
Do you belong to a group of traders that post key levels based on their technical analysis to be utilized for trading opportunities?

How it works
Simply enter the values of the key levels that you would like to plot horizontal lines for

Settings
You can enable/disable any of the levels
You can change the colors of the levels
You can add Previous Day High and Previous Day Low levels to the chart

Limitations
Currently the levels (besides PDH/PDL) are hardcoded to only display for the SPY security "AMEX:SPY"
