Channel and Extreme Support for strategies module

I wanted to know if I set my settings on spreads to always buy do the channel% and extreme% calculations take this into effect. I ask because I have been seeing some spreads saying they are over 100% in the Chann% column but are not below the channel. Maybe I am not understanding what the number means.

Hi Pez, give me some spread example which you think doesn't match and I will try to explain. Always buy calculates chann and extr correctly.

This came up as 115% on the Channel% colunm.

This would be one example Roman.

OK, I see what you mean. Channel works with average values max/min peaks of all years. I draw lines for you in HG example (I estimated Y position of lines). Channel (blue lines) works with all data, CChannel (Current Channel) cuts data based on the last day of current spreads. So we have top of the channel (0%) and bottom of the channel (100%). When current spread is below channel, value is >100%. Calculation with averages is not really something sophisticated, so sometimes top/bottom of the channel fits good (all years are moving nicely in channel), sometimes not (a lot of extremes, years are spread across whole stacked chart) . But points is, when you are >100%, you have always some space for profits. I personally use Extremes.

SI-GC, is in principle the same, top of the channel would be little bit above 0, and bottom around -15000.

Hope it's clear now?
