Coral Trend Indicator

[wp_ad_camp_5]

 

Coral Trend Indicator is yet another trend following indicator inspired by Tradingview Pinescript code. Code is designed to plot in PSAR style. Green color dots represent a bullish trend. and the red dots represent a bearish trend. Coral trend applied to Nifty EOD charts as shown in the above figure.

Looks like the system is quite popular in the MT4 platform among FX traders known as THV Coral. Whatever the code does is just the indication of the trend and not a complete system though. Do your homework if you would like to build some system on top of it.

  1. Hi, I found in Ami 5.60.2 that when you zoom in to a chart the red and green dots are shifting. In such a case the indicator is not very reliable. Brgds, CArnot

  2. Hi,

    The download link gives the same code with repainting problem. Please update the link. Enjoy, CArnot.

  3. hello sir i am regular reader and follower of your AFL and POSTs lot of thanks
    sir my humble Request sir please prepaire to this AFL in to MULTI TIME FRAME ( Not MTF DashBoard ) means when we select 5 min chart but indicator play like 15 min s Data based , and 15 min chart like 60 min …………,
    sir i found like this supertrend in MQ4 but not in Amibroker so please ……………prepaire this AFL ( Coral Trend Indicator) in MTF i hope response possitively thankyou sir

  4. Yes It would be excellent if Coral can be coded for multi time frame.
    Which means the buy signal would be generated in 5 min chart when 15 min chart turns green and in reverse sell would be signalled in conjunction with 15 mind chart or 30 mins chart.
    Even if there is a way to notice coral trend higher time frame indicator in lower time frame it would be excellent.

  5. Not better use this function instead looping.

    function T3( Price, T3Periods, s )
    {
    e1 = AMA( Price, 2 / ( T3Periods + 1 ) );
    e2 = AMA( e1, 2 / ( T3Periods + 1 ) );
    e3 = AMA( e2, 2 / ( T3Periods + 1 ) );
    e4 = AMA( e3, 2 / ( T3Periods + 1 ) );
    e5 = AMA( e4, 2 / ( T3Periods + 1 ) );
    e6 = AMA( e5, 2 / ( T3Periods + 1 ) );
    C1 = -s ^ 3;
    C2 = 3 * s ^ 2 * ( 1 + s );
    C3 = -3 * s * ( s + 1 ) ^ 2;
    C4 = ( 1 + s ) ^ 3;
    T3Result = c1 * e6 + c2 * e5 + c3 * e4 + c4 * e3;
    return T3Result;
    }
