Hi, speculants!
Can anyone help me with issues?
1.Seems there is a bug in 240 timeframe counting, the script does not indicate divergence
2. If I set bigger length value to find_diver(m240, 200) it says "out of depth at index"
3. I can't undestand why plotshape() does not plot label "Diber!" on graph. May be I have to set any more parameters?
4. How can I call "plot" functions in cycle? I want to write something like this:
for timeframe in
count_and_plot_diver(timeframe)

Thanks!
