Don't try to act like your simple differential equation is somehow obscure, nub.
the equation itself is not obscure. its application in this way perhaps may be. i certainly have only seen one other poster make the connection i just made, and the model im referencing is a little bit more complex than just mapping this equation to the price.
further, as i have butt heads with many posters here about the value of technical analysis, it seems that a firm grasp of even regular calculus is not incident in the majority. so while this equation may seem extremely familiar to you (and i, as well), it is relatively obscure as far as i am concerned if many here would require significant explanation to stomach it.
anyway, apologies for any perceived esotericism.
