Well, yes S~1 isn't great but it's a fair bit better than "long and hope" where stocks or bonds alone might have a sharpe of 0.3 over the long term. Still, if you're looking to raise real money, I'd aim for 2+ with enough track record they can believe it's representative (a couple years). The reason you're getting a low S is because of your few big positive days. These are a long way from the mean daily return and jack up the standard deviation a lot (proportional to the square of the difference).
Another way to interpret the Sharpe ratio is that is would take an "S standard deviation event" for you to lose money during a single year period. Of this interpretation, like many aspects of the Sharpe ratio, assumes a normal distribution, which is far from true for the market and very far for you.
This one will be better for you:
Yes, 200 is ridiculous for a Sortino (or Sharpe, basically same scale). Your interpretation is right (about the typical small loss), but the statistics aren't that smart. You see on average you've managed to be up during the period, so the mean is positive overall. This means the stats think you almost always make money, but in practice you've made a bunch of high risk, high return bets where you managed to win twice. Generalizing that is difficult / premature without a lot more data.
