Writing codes and testing them is a very good educational tool so even if you never write a winning strategy it is worth sticking with. By trying different things we get to see what works better. We can quickly get a feeling for how tight stops can kill a strategy and whether some markets are good for trending or better for mean reversion. We can work out whether longer time frames are better than shorter time frames for our type of trading. The actual strategies coded may be failures but they all teach us something that makes our trading better even if we only ever manually trade. Slowly slowly we become better traders than we would by just staring at a chart everyday and watching the candles go up and down.
