Hi all! I tried following the tutorial on youtube.

However I have encountered an Error message stating that there are no suitable methods to override. I tried searching up online and reading the API documentation but I still have no idea how to correct my mistake. Any help would be much appreciated !  THANK YOU

public override void OnTradeBar(Dictionary<string, TradeBar> data) { decimal price = data[symbol].Close; emaFast.AddSample(price); emaSlow.AddSample(price); if (emaFast.EMA > emaSlow.EMA){ Order(symbol, 100); } else if (emaSlow.EMA > emaFast.EMA){ Order(symbol, -100); } }
