Hi Alex,

Source code is not available unfortunately. But the formulas for most of them are publicly available and easily discoverable.

Best Regards,

If you made the sources available like TradingView.com it would make it far easier to edit our own custom indicators.

For example you have no option to set RSI or Stochastic RSI source as OHLC/4

Hi Alex,

You can any indicator as an input to RSI or Stochastic RSI. If you add an indicator on the chart, then it will appear on the Source list. See below

But as you can see there is no option for Open+High+Low+Close divided by 4 for a smoother curve - this is why I need the default script so I can write it in myself. :)

Hi Alex,

You can write the OHLC/4 indicator and feed it to the RSI. You do not need to develop the RSI from scratch.

Hi Alex,

Here is the indicator

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class OHLC4 : Indicator
    {

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }


        protected override void Initialize()
        {
            // Initialize and create nested indicators
        }

        public override void Calculate(int index)
        {
            // Calculate value at specified index
            Result[index] = (MarketSeries.Open.LastValue + MarketSeries.High.LastValue + MarketSeries.Low.LastValue + MarketSeries.Close.LastValue) / 4;
        }
    }
}

Create it and add it to the chart. Then when you will add RSI, it will show up in the Source list. See below

Best Regards,

One last question - how can I add OHLC/4 to Stochastic source?

PanagiotisCharalampous

Hi Alex,

You cannot add it to Stochastic since Stochastic does not use such type of sources to be calculated. The calculation of Stochastic requires candlestick information. You can find the formula here.

On TradingView.com it is possible to point Stochastic RSI to OHLC/4 - is there any plans on adding it as a built in indicator?

Hi Alex,

Stochastc and Stochastic RSI are different indicators, Here is the Stochastic RSI for cTrader. Is takes a hardcoded MarketSeries.Close as input but you can easily tweak it to take it as a parameter and use OHLC/4 instead.
