It has been five days since the mass closure of channels based on the principle that if there were no payments, neither outgoing nor incoming, in a channel within the last 14 days, I would close that channel.

I accomplished this by retrieving the ForwardingHistory list from the LND server, which returns a structure from which you can determine the channel to which a payment was sent and from which it was received. We take these fields and the timestamp available in the same returned structure and create our own virtual structure with lists of channels, the time of the last payment, and a counter of how many payments occurred over the past set number of days within that time window.

Experience has shown that despite closing approximately one-sixth of the channels by capacity, the number and amounts of daily transactions did not decrease—in fact, they may have even slightly increased. However, I believe this could simply be due to daily fluctuations. As a result, I am satisfied with the channel closures; the focus has shifted from quantity to quality.
