No Demand bars appear a lot more often than No Supply bars - is this normal?

No, not necessarily
The current trend makes a fair bit of difference, as you will usually see 'true' No Demand after weakness (serious selling), or when price is trading under a negative influence and is in a downtrend (and when you see a NS bar after some sort of decent supply event, it will often be the seller easing back on their supply, in preparation to give price a push back up, before resuming the selling again).

You will see 'true' No Supply after strength (serious buying), or when price is trading under a positive influence and is in a uptrend (and when you see a ND bar after some sort of decent buying event, it will often be the buyer easing back on their demand, in preparation to give price a push back down, before resuming the accumulation again).

So the indicator needs to be 'in the right place' and 'in the right context' (after buying or selling).
If the indicator is NOT 'in the right place with the right context', it is usually doing something else (often just 'marking time, because the market is not favourable - for whatever reason - at that point in time). So the bars may just be coincidentally appearing like a ND or NS bar.

Does that make sense ??

----------------------------------------------------------

so anyway, most of those bars seem OK, there might be a few (minor issues) with a few, which I will attempt to explain later......
