Here's the error I get
I can't implement the onTick method and get the price of previous bars because the related lines of code are marked in red.
protected override void OnTick() // I have an error on onTick
{
double v1 = Bars.ClosePrices.Last(1); // I have an error on Bars.ClosePrices
double v2 = Bars.OpenPrices.Last(2); // I have an error on Bars.OpenPrices
Print(v1);
}

Hi there,
OnTick() is a method of a robot, not of a plugin. Same for Bars property. Here is a starting point for handling tick events and accessing bars in a plug in
using System;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
namespace cAlgo.Plugins
{
[Plugin(AccessRights = AccessRights.None)]
public class Test : Plugin
{
Bars _bars;
Symbol _symbol;
protected override void OnStart()
{
// To learn more about cTrader Automate visit our Help Center:
// https://help.ctrader.com/ctrader-automate
_bars = MarketData.GetBars(TimeFrame.Minute);
_symbol = Symbols.GetSymbol("EURUSD");
_symbol.Tick += _symbol_Tick;
}
private void _symbol_Tick(SymbolTickEventArgs obj)
{
Print(_bars.ClosePrices.Last(1));
}
protected override void OnStop()
{
// Handle Plugin stop here
}
}
}Best regards,
Panagiotis

There is an error on this line : Print(_bars.ClosePrices.Last(1));
_bars doesn't know the methods or ClosePrices.Last and therefore fails to call them.
_bars. doesn't call any method, hence the error
