Bearish divergence: 

• HBT
• HTB 

Bullish divergence: 

• LBT
• LTB 

hi Igor 

I just bought this indicator, when I install it on the chart, only the divergence lines in the main window appear.

 The window indicator does not appear as seen in your videos.

When switching to different timeframes, an alert window will appear informing: (Not enough bars. The indicator is inactive.)

Hi!

Please read the description of the product carefully. All your questions are already answered in the description.

Additionally:

1. Switch timeframes to check how many bars have you got.
2. Load base indicator in subwindow (for example RSI)
3. Load Bearish CD HTB Osc indicator on the main chart
4. Check if your input parameters are in accordance with RSI indicator input parameters (They should be the same)
5. If everything is correct the lines will apper in both windows (main and subwindow)
