I am using Tradingview with Tradestation, When I login to Tradestation through Tradingview and attempt to trade it says - NON tradable symbol - I trade MESM21 (Micro Mini S&P500). Why is what? how to fix it?

The reason I went with Tradestation is their Salutes program which gives discounted(0.45$) rate for futures. I had Tradovate before but it appeared that execution was slower/worst that on the Tradestation.

Also, anybody uses Tradingview here and why/why not?

Thanks

Hi, I don't use this combination, but have you already tried to use the classic CME-symbol: MESM1 instead of the TradeStation-symbol (MESM21)?
