Hello,

Yes, I have tried this in several time frames, from daily to 30 minutes. The best results are when the daily trendlines are used as a reference for the lower time frames.

Also, the lower the time frames, the least certain one is about the overall trend, so I tend never to use time frames lower than 1 hour.

Now to explain the other question, no, I do not switch to candle charts to check if a trend line has been broken or retested. For that I only use line charts, that is the key to this method.

I only switch momentarily to candle charts when I need to ascertain if a price target has been reached by the HIGH or LOW, which is (of course) not seen in line charts.

I hope this helps.
