We Got a Buy Signal after 8 months of bear phase - is it going to be correct prediction?

After 8 months being in bear phase -methodology gave first buy signal. The signal came on 7th January although analysis was done Yesterday. And it has not changed since then despite market going down since then as seen in below image

So far the signals from methodology are 100% correct. I have no idea if this signal will be true or not. Or it will be reverted soon to sell as has happened once in past from sell to buy. So I will do this analysis now more regularly.

The methodology was posted in post - data provided by santiment improves trading profitability. Please refer to that for details about the methodology.

Using that methodology along with data from Santiment for 34 ERC20 assets - I see excellent results with nearly 15 times return for a year. What is interesting is that last sell signal came on 8th May 2018 and it continued till 7th January 2019.

Note - This is not an investment advice. I do this analysis out of my interest.
