Hi all,
Hoping someone can help.
I'm trying to creata a bollinger band bot and I think its going okay. I've moved the things like LTP, MA, UPPER AND LOWER bands into histroy list so i can watch whats its doing however, it looks like the picture. and im not sure what Im doing wrong.
I've gave it to chat GPT and says all looks good with the logic, however said in the imagine below. I know that doesn't help much really. I need someone to look over it really whos made their own and just correct it/point in in the right direction to tell me what i need to do. But its 95% there. Dallas I have sent you a DM if you're okay to proof read my bot. but if anyone else can share A hand I'll send it to you
thanks again

I had a look into this a while ago (from an automation point of view) and ended up going for "The Extreme Value Method for Estimating Variance".
The context being:
- it is generally accepted that, at least to a good approximation, In (S), where S is the price of a common stock, follows a random walk.
- The diffusion constant characterizing that walk for each stock thus becomes an important quantity to calculate
The extreme value method of calculating the diffusion constant (d) is relatively easy to calculate and just a matter of calculating max & min price(s) over set time intervals which is easily automated.
The issue I found is that for most trading situations "d" is NOT constant and the the max / min samples are too few over the time period where the d could be expected to be constant.
You can find more info here on it if still interested:
