Okay since no one cares about fixing this indicator, I'll throw in my methodology.

Chart 30m

HighestHigh_LowestLow : 15 15

Manual calculation:    1.  On current developing candle, calculate the average between upper band and lowerband

Plot in manually the median band

1.  If price is higher than the median band,  it is a buy bias

2. If price is lower than the median band, it is a sell bias

There are 3 more indicators using them as filters  that I will share when someone helps me alter this indicator. 

Check it out yourself, you may able be able to figure you what the other indicators that I am using.

I have been using this methodology for 9 months now with success.

To sum up.  There will be additional 3 lines equally distributed between current bands.

The way i do it is that on the current candle, I calculate how many pips between the current high band and low band, then divided it by 2, then i add the result to the to the lowest band -- this it is my middle line

For example:

Upper band is 160.60

Lower band is 160.20

total pips between bands= 40

40 divided by 2 is 20

I then add .20 to 160.20 ..   equals 160.40  (this is my middle line)

For manually plotting the other two bands (option 2 )  I apply the same logic and calculation.  So this is really a hard work plotting it manually.   i really appreciate your help on this on.

Thank you

I really appreciate your assistance on this indicator.   Currently, I do this manually and it is a pain doing it.

Thank you so much, developers.  Your hard work is very much appreciated

Request 1 (option 1)

Can you please add option to have an average line (middle band) to be plotted between existing bands

Request 2 (option 2)

If possible can you also add option to plot the average between middle band highest high and plot another band with the average between middle band and lowest low band.

Thank you so much for your help.
