I’ve had several requests to code various indicators designed by Tom DeMark and here is one such study. The DeMark Pressure Ratio indicator seeks to quantify accumulation/distribution through a combination of volume and price action. The short entry is indicated by the oscillator exiting from above the overbought line at 75 with the long entry indicated by a rise above the 25 oversold line. Also pictured is the soon to be released ThinkScripter Volumetric Trendline study which automatically plots in real-time a volumetric trendline for the user selected period. Pictured on this chart of the /ES are 20, 55, 110, and 250 period volumetric trendlines. Stay tuned 
Both studies will be added to the member’s bundle this weekend.

What kind of buy/sell trigger do you have there?
It’s a custom one I did for one of our PRO members.

Eric, what are those labels and numbers on price chart? TTLE, TTLX, -50 etc.
Those are a thinkorswim strategy running in the background. It provides a crude backtesting capability.
Thanks.. Would you know the syntax of writing such labels near ends of price bar?
Those labels are only available through a strategy. You can add chart bubbles using the addChartBubble() function.
