The indicator can be used to detect the direction of the trade. Looks, for example the following trade system for details.

Hi,

Thanks so much for this indicator, it works really well, my only query is how come it doesn't load for the entire length of a chart..it seems to only show for a short time length..is it suppose to be that way?

Thanks :)

Yes. The indicator is drawn for the last N (where N is the first parameter of the indicator) bars only. Moreover, the indicator completely redraws all last N bars when a new bar appears.

any possibility of getting a version of this indicator that doesn't repaint on every new bar?

No, because such class of the indicator (the same is, for example for any approximation indicators or to the wave analysis) always does it. It is specific of the method.

This indicator seems to work quite well. I tried to make a signal but my knowledge is not enough for this task. Here is the code which does not work correctly. It generates signals but not in the right places. Signals must be generated when price touches L3 (L4) or L6 (L7).

Dear Nikolay, maybe you can help?

Code: Select all
-- Indicator profile initialization routine
-- Defines indicator profile properties and indicator parameters
function Init()
    strategy:name("Gravity signal");
    strategy:description("Signals when Price hits Gravity Edges");

    strategy.parameters:addGroup("Gravity parameters");
    strategy.parameters:addInteger("N", "Number of bars", "", 120);
    strategy.parameters:addInteger("O", "Order", "", 3);
    strategy.parameters:addDouble("E", "Eccart value", "", 1.61803399);

    strategy.parameters:addGroup("Price parameters");
    strategy.parameters:addString("Period", "Time frame", "", "m1");
    strategy.parameters:setFlag("Period", core.FLAG_PERIODS);

    strategy.parameters:addGroup("Signal parameters");
    strategy.parameters:addBoolean("ShowAlert", "Show Alert", "", true);
    strategy.parameters:addBoolean("PlaySound", "Play Sound", "", false);
    strategy.parameters:addFile("SoundFile", "Sound file", "", "");
    strategy.parameters:setFlag("SoundFile", core.FLAG_SOUND);
    strategy.parameters:addBoolean("Recurrent", "RecurrentSound", "", false);

    strategy.parameters:addGroup("Email Parameters");
    strategy.parameters:addBoolean("SendEmail", "Send email", "", false);
    strategy.parameters:addString("Email", "Email address", "", "");
    strategy.parameters:setFlag("Email", core.FLAG_EMAIL);
end

-- Indicator instance initialization routine

-- Parameters block
local gSource;

    end

    assert(not(PlaySound) or (PlaySound and SoundFile ~= ""), "Sound file must be specified");

    RecurrentSound = instance.parameters.Recurrent;

    name = profile:id() .. "(" .. instance.bid:instrument()  .. "," .. N .. "," .. O .. "," .. E .. ")";
    instance:name(name);

    if onlyName then
        return ;
    end

    assert(instance.parameters.Period ~= "t1", "Can't be applied on ticks!");

    gSource = ExtSubscribe(1, nil, instance.parameters.Period, true, "bar");
    BELCOG = core.indicators:create("BELCOG", gSource, N, O, E);

end

function ExtUpdate(id, source, period)
    if id == 1 then
        BELCOG:update(core.UpdateLast);

        if period >= BELCOG.DATA:first() + 1 then
            local message = nil;

            if core.crossesOver( gSource.high, BELCOG.L3, period) then
                message = "Gravity OverBought";
            elseif core.crossesUnder( gSource.low, BELCOG.L6, period) then
                message = "Gravity OverSold";
            end

            if message ~= nil then
               if ShowAlert then
                   terminal:alertMessage(instance.bid:instrument(), instance.bid[NOW], message, instance.bid:date(NOW));
               end

               if SoundFile ~= nil then
                   terminal:alertSound(SoundFile, RecurrentSound);
               end

               if Email ~= nil then
                   terminal:alertEmail(Email, name, name .. "(" .. core.formatDate(instance.bid:date(NOW)) .. ") : " .. message);
               end
            end

    end
end
