%%Agree, but it's still not an edge on the market... just on other traders.... who are neither as smart nor a disciplined as you.
Making money in the market is not quite the same as "doing better than other traders".
One of the best reads on an edge is named = Market Makers Edge by MS ,market maker Joshau Lukeman.And its much , much more than making money on the bid /ask. I ignore most of the outdated fractions, in that book -except 1/2[ 1/2 or 50 % seems still helpful sometimes].
