The best way to not get wrong results is avoiding the use of wrong facts.

I don't need any published hydroxide price because I'm not making predictions. Just waiting for industrial agreements and sales to happen. You need prices to make predictions (you may tell us your reason for that, as you're not one of the potential lenders nor a shareholder). But as you don't know the terms of the agreements between LTR and offtakers, you are doomed to extrapolate. So the accuracy of your conclusions is the same as those got from a crystal ball.
Moreover, you want us to believe in an index that is considered to be manipulated (SMM), or similar ones (Fastmarkets) that don't explain the measurement conditions: mean prices or ranges should be supported by the number of observations/measurements -deals-, amount of tonnes, etc... If Fastmarkets tell us nothing about these parameters is because that allows them to give you a range of prices obtained, for example, from two deals for 5,000 tonnes each. That means nothing for the market.
