Need some help with FirstTickOfBar

[grd974]

Hello,

I wrote that code and used it with Market Data replay as of January, 26; although it plots as expected outside the timespan of that particular trading day, it always plots the same colour during the replay.

I welcome any help.

        protected override void Initialize()
        {
            CalculateOnBarClose	= false;
            Overlay				= false;
            PriceTypeSupported	= false;
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
			if (FirstTickOfBar)
			{
			if (Close[0] > Open[0])
				BackColor = Color.Blue;
			else
				BackColor = Color.Yellow;
			}
		}

Gerard, are you saying that, when played on a Market Replay, FirstTickOfBar doesn't work correctly? FirstTickOfBar is generally used to reset variables and such, not as a marker to set drawing properties.

Wel, thanks for sharing this.

I have a 15 minutes candlestick chart which I "backcolour" PaleGreen when the candlestick is green and LightPink when the candlestick is red.
Having set CalculateOnBarClose to false, I wish to check out on a tick basis whether the previous one or couple of candlesticks were green or red.
Do you have any clue to do so ?

Since green = an up candle and red = a down candle, test for that. To test the previous candle:

if(Close[1] > Open[1]) //if true it was a green candle


if(Close[1] < Open[1]) //if true it was a red candle


Then you are left with the doji situation: Close[1] = Open[1]

I don't understand the tick by tick basis check because previous candles will not change. The only one that will be changing with ticks is the current candle, which can be tested the same way.
