I found out Schwab screwed up the math with the do

I found out Schwab screwed up the math with the dollar cost average of all my shares since the shares have been purchased over such a long period: pre reverse, post reverse and now post dividend. While I sold a ton and banked a nice profit, it turns out the shares I had left are at $1.98. I added a bit today and a small bit last week. Even $1.98 seems a far ways off as of now on those old shares. Guess I am still an investor vs a trader.
