How to get Price change percent from ticker

There is problem to get Price Change Percent from ticker because the limited variable set in ExchangeSharp.ExchangeTicker class. So how we get Price Change Percent from ticker

public sealed class ExchangeTicker
    {
        public ExchangeTicker();
        public string Id { get; set; }
        public string MarketSymbol { get; set; }
        public decimal Bid { get; set; }
        public decimal Ask { get; set; }
        public decimal Last { get; set; }
        public ExchangeVolume Volume { get; set; }

        public void FromBinary(BinaryReader reader);
        public void ToBinary(BinaryWriter writer);
        public override string ToString();
    }

What I like about the GetCandlesAsync approach, you basically can get any time frame you want. Here’s BSVUSD at one hour intervals. I have it on a timer that refreshes every minute or every hour depending on the candle.

Edit: Percent calc fix

Alternatively, use GetCandlesAsync to get any price history using candle data.
