Hi.

I'm looking to see if implementing this into thinkorswim as an indicator would be possible.

It is the acceleration of the bid/ask ratio from one minute to the next. So if the bid/ask ratio was 10-1 at two minutes ago, 20-1 at the previous minute (increase of 10 per min), and 100-1 at the current time (increase of 80 per min), then the rate of acceleration of the ratio would be 70 (80pm - 10pm). I would also like the calculation to only include the orders within a 5% range of the last price
example shown:


I've seen similar things done as studies except they were visual and I want a numerical representation for more precise observations. They also were not the exact calculation I want.

Also, I am new to thinkscript. I have not created my own thinkscript (I don't know how to write code yet). I have inserted the scripts of others to add new studies and indicators. So I apologize in advance if something like this already exists.

Is any part of this indicator possible to create?

your words say bid/ask.
your picture formulas imply bid SIZE / ask SIZE
do you want size? edit your post.

size is not a data that can be read by thinkscript, so it can't be done.

in excel, you could use some RTD() formulas and VBA, to read prices and keep some, in order to do this
