There are many modifications of the Channel Trading system.
Some people are using this channel together with zigzag indicator. What is the difficult case we should have if we are using the channel togather with zigzag?
As far as I know there are many kinds of indicators:
1. Normal one. These indicators are not painting the past and refreshing by itself with no problem.
2. Indicators which are working on historical data only. These kind of indicator is not refreshing. Because it was programmed like this especially.
3. Indicators which is valid on the current data only and not valid on historical data. These indicators are painting the past. But it was programmed like this especially.
4. Some modifications of the items 2 and 3. For example: Zigzag indicator (recent high or low is not valid and previous high or low is not valid as well), SHI_SilverTrendSig and SHI_SilverTrendSig1, Float indicator and some other indicators.
