On the weekly or daily?

I generally offer to use the 100 day SMA but since I'm usually buying online at spot and selling IRL I have to be careful

The real price is the most that someone will pay me for them.

I prefer to take the volatility out of the equation because I play the long game

Well, the the problem is, if the SMA is lower than spot, people love to buy from you, but you're not buying st that price. It's only downside for you. It's an unstable state, if everyone doesnt agree to use it as the price, it's not the price. And if everyone did, there would be no divergence.

in all things digital this is reasonable. because im impatient i like a ladder of 10, 30, 60, 100.

easy enough to vibe code a get price, get ladder sma price at each, buy/sell qty/price
