Thermometer Oscillator
This one comes from David Bowden's Gann trading material — a quick way to check whether a trend still has gas in the tank or is about to stall. I built it as a simple momentum readout, nothing fancy.
Each bar gets scored on three things, added up into one number from -5 to +5:
1. Today's close vs. yesterday's close — +2 if higher, -2 if lower, 0 if it didn't move.
2. Today's close vs. today's open — same idea, +2/-2/0.
3. Today's range vs. yesterday's close — +1 if the whole bar sat above yesterday's close, -1 if it sat entirely below, 0 if yesterday's close landed inside the bar.
Add the three up and you get a number between -5 and +5. It plots like an RSI, with lines at +5, +3, 0, -3 and -5 so you can see where things stand at a glance. There's also a moving average on top (EMA by default, 9-period, but you can switch to SMA/WMA/RMA and change the length) to smooth out the noise.
Don't trade off this thing alone. It's an early-warning tool, not a signal. The way it's meant to be used: watch for it disagreeing with price. If a market's been sitting at +5 for a few days and then drops to +1 while price is still grinding out higher highs, that's momentum leaking out before the chart shows it.
Bowden's original write-up covers the daily version — previous day vs. current day. He does the same thing for the weekly trend, but you don't need a second calculation for that, just flip the chart to a weekly timeframe and read it the same way.
Educational tool only, not trading advice. Do your own homework before putting money behind it.
