Help setting stoploss below/above previous candle low/high

I am trying to make the bot execute and set stoploss at the low of last bar like the way in the code below.

Suprisingly the bot places stoploss at  around 1.6pips from entry price on every position instead of below the low of previous bars. i dont even know where the 1.6pips valiue comes from.

here is my code please help. 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
    public class EMAcBot : Robot
    {
        private ExponentialMovingAverage ema;
        private MarketSeries series;

        protected override void OnStart()
        {
            // Initialize the EMA from 1-minute timeframe
            series = MarketData.GetSeries(TimeFrame.Minute);
            ema = Indicators.ExponentialMovingAverage(series.Close, 8);
        }

        protected override void OnBar()
        {
            // Access the last closing price from 1-minute timeframe
            double lastPrice = series.Open.Last(1);

            // Use the EMA and lastPrice in any timeframe
            if (ema.Result.HasCrossedAbove(lastPrice, 1))
            {
                // EMA crossed above lastPrice

                ExecuteMarketOrder(TradeType.Sell SymbolName, 1000, "1min", Bars.HighPrices.Last(2), null);

                Print("EMA crossed below lastPrice!"); // Printing a message to the log
                // Do something
            }
            else if (ema.Result.HasCrossedBelow(lastPrice, 1))
            {
                // EMA crossed below lastPrice

                ExecuteMarketOrder(TradeType.Buy, SymbolName, 1000, "1min", Bars.LowPrices.Last(2), null);

                Print("EMA crossed below lastPrice!"); // Printing a message to the log
                // Do something else
            }
            


        }
    }
