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);
}
}

The tutorial on YouTube is quite old. The OnTradeBar method was deprecated.
You need to use OnData instead:
public override void OnData(Slice data) { var price = data[symbol].Close; emaFast.Update(Time, price); emaSlow.Update(Time, price); if (emaFast > emaSlow) { Order(symbol, 100); } else if (emaSlow > emaFast) { Order(symbol, -100); } }Please checkout the documentation that is kept up to date.

Thats an old code sample. Take a look on the samples in the university (algorithm lap).
You can find there: "Strategy Example: Moving Average Cross Strategy" and clone this.
Also go through some strategies the community provides to take a look on same good samples. If you search in the community there are some cross over strategies you could clone and play with.
below is a working example of ma cross over
Jared Broad btw the ma cross strategy doesnt work because of the :
int holdings = Portfolio[symbol].Quantity;
The ma sample above could be from your youtube video :)
