I've been using DeepSeek for strategy development these past few days. It feels better than Gemini; it provides detailed explanations of various aspects of the strategy. However, Gemini's approach to trading strategies is somewhat simplistic and vague. But its code implementation is far superior to DeepSeek's. DeepSeek's code sometimes backfires. Instead of providing a solution to a problem, it presents you with ten possible solutions, which is verbose and redundant. To put it simply, a problem that Gemini can solve twice, DeepSeek might explain multiple times without providing a clear solution.
