Best Solana Price Charts for Accurate Trading on Jupiter or Raydium?

I’ve been trading on Jupiter via my Phantom Wallet, and I’m using MEXC charts to track prices. However, I’ve noticed that even when the price moves past my set buy/sell limit, my orders on Jupiter aren’t triggering. Given that Solana has other aggregators like Raydium, would it be better to use Raydium for more accurate or faster trades? Also, which price charts or data sources should I follow to get the closest price feed that matches what these aggregators (Jupiter or Raydium) are using for execution?
