Different values on chart and in cBot

Hi,

I am using indicator "Sample Envelopes Cloud" and the values on chart and in cBot's logs are different.

I saw the similar thread but it doesn't answer to my qeustion.

Both the chart and the bot have the same indicator settings.

Could you please tell why there is a difference on real market? As it happens I have observed this differences on BTCUSD, other tests on WTI, EURUSD seems to have proper values.

namespace cAlgo.Robots

    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
    public class Envelopes : Robot
    {
        [Parameter("EnvelopeOne", DefaultValue = 0.8)]
        public double EnvelopeOne { get; set; }
        [Parameter("EnvelopeTwo", DefaultValue = 1.5)]
        public double EnvelopeTwo { get; set; }

        SampleEnvelopesCloud _envOne;
        SampleEnvelopesCloud _envTwo;

        protected override void OnStart()
        {
            _envOne = Indicators.GetIndicator<SampleEnvelopesCloud>(20, EnvelopeOne);
            _envTwo = Indicators.GetIndicator<SampleEnvelopesCloud>(20, EnvelopeTwo);

            Print("Env1 Up: " + _envOne.UpperBand.LastValue);
            Print("Env1 Lo: " + _envOne.LowerBand.LastValue);
            Print("Env2 Up: " + _envTwo.UpperBand.LastValue);
            Print("Env2 Lo: " + _envTwo.LowerBand.LastValue);
        }
