What did I go incorrectly? I sold at near the top, earned a profit from ETH interim, and repurchased before the breakout from the pullback?

How could one improve upon the trade I did?

Btw, when I sold LTC it wasn't really an attempt to day trade, but rather I wasn't sure if one of the miners might tweet something to crash the price, so it was a precautionary move to see how the pullback developed. I had been wanting to trade into ETH next. When I saw that the LTC pullback was a wedge, then I felt confident to re-enter, which I did at a gain in both BTC and LTC. What fault can you find in that trade?
