I've got issues/questions about FOREXCOM

• I've connected through my broker, but I see a "Non-tradable symbol" error message when trying to trade
• FOREX.com trading - how to start & how to place orders
• Why was my order executed/not executed, although the price on the chart reached or didn't reach the order level?
• I have an MT4/MT5 Forexcom account. Can I trade with it on TradingView?
• I have an DMA/STP Pro account. Can I trade with it on TradingView?
• Why are Stop Loss/Take Profit orders unavailable for market orders/individual positions?
