I just bought shares now what do I do?

Hello everyone:

I am new to trading, very new! I recently bought a very large amount of shares of Thunder Energies $TNRG and it has made some runs twice and made some gains. I bought them at a very low price and they have a made some gains but what do I do now? I am at a loss of when to sell or how much? After that what do I do, what do I buy and how much? For any guidance on what I should do next I would be grateful!

Well, I own about 1 million shares. The dates are a little foggy but for about 3 months I have had them.
