Volume Gradient + Heikin Ashii Trend Indicator

Recommended Posts

In the spirit of the current interest in volume-based indicators, I wrote this TradeStation hybrid of Volume Gradient and Heikin Ashii Trend. It will create a chart with two distinct ranges of colors. One color range, defaulted to green, indicates an uptrend--the other, defaulted to red, indicates a downtrend. The relative darkness of each color reflects the amount of volume in a particular bar relative to a previous sample average. The number of bars in the sample both for determining the trend and the average volume is the same and is set by the input parm Length.

 

Since PlotPaintBar takes RGB color numbers, to provide the full range of colors, the inputs to this indicator allow a completely customizable red, green and blue setting for each end of each color range. For example, UpHR = The uptrend, high volume red component, UpHG = the uptrend, high volume green component, and so forth. DnLB = the downtrend, low volume blue component, and so forth.

 

You can use any typical Windows color selection dialog box to select colors and find out the Reg, Green, Blue component numbers for the color. (See the sample picture.)

 

I suggest using washed-out colors for the low volume colors and rich colors in the same basic color for the high volume colors. For example, faded pink to deep red. But of course you can do whatever makes sense to you and looks good to your eye.

 

(Note that the algorithm used for determining trend is not exactly the same as TTM trend, but the results are pretty much the same.)

 

Hope this helps!

You have had a great idea... Thanks!

 

I wonder if there would be a way to show the volume like a thermometer on each candle? If you could use up volume on all candles but show it like water in a drinking glass? The difference would be down volume. That would be special.

Guys,

 

Thanks for your interest in this indicator.

 

Here's a new version. It adds an input that allows you turn off the trend indicator and just paint normal up and down bars albeit with the volume shadings.

 

Also, IMPORTANT, I discovered that for the colors to show consistent density they must parallel each other. This is hard to explain, but if you look at the settings below you can see what I mean.

 

UpHR(0),

UpHG(135),

UpHB(0),

 

UpLR(205),

UpLG(255),

UpLB(205),

 

DnHR(135),

DnHG(0),

DnHB(0),

 

DnLR(255),

DnLG(205),

DnLB(205);

 

Without this you will have problems with similar relative volumes showing inconsistent shading between the up and the down versions.

 

Please note that you have to delete the indicator and re-add it after installing the new version or it will use your old color settings.

GCB, just so I understand how to use this correctly, the winner of the up/down volume battle gets the candle. And... if the winner won the candle overwhelmingly, the color is darker. Light color for a close call.

 

Is that correct? I think I like it better without the trend. You have done a great job with this. Two thumbs up!

Robert,

 

Thanks very much.

 

Actually, the way it works is this: If the candle is an up candle--that is the close (or current) price is greater than open price--then the density of the candle color is based upon the amount of up volume for that candle relative to the average of up volume for the preceding n candles, where n is set by the VolLength input. Vice versa for down. So up volume is only compared to up volume, and down is only compared to down. So if an up candle is dark it means it had quite a bit more up volume than the average of the preceding n candles' up volume.

 

Since each candle gains volume as it is being formed you will not know the end color of a candle until either it reaches its darkest possible color or the next candle begins. Practically all candles start out light colored.

 

When the trend indicator is in an uptrend all candles are green, whether they are up or down candles, and in a downtrend all candles are red. Even so, up candle volume is only compared to the average of up volume, and vice versa. The PriceLength input is used to determine the moving average for the trend determination.

 

Note also that this can only be used on intraday charts. Daily charts or larger do not differentiate between up and down volume on TS.

Excellent.

 

You said PriceLength is used to determine the moving average for the trend. May be a dumb question but how does that work? Does this mean we can adjust the sensitivity, i.e. when the trend bars change color?

 

I was looking at a few volume "share bar" candle charts with this indicator. It appears to be working correctly with those too. Also I was thinking that your above explanation would be good to include inside the eld. Maybe a little credit for yourself too. :) Nothing wrong with putting your name on your work.

Yes, a longer PriceLength will find longer more sure trends, will but have a larger lag. A shorter PriceLength will locate trends faster, but will give more false signals. Such is the nature of trendfinding.

 

This indicator considers it a change to a downtrend when a point on the moving average is lower than the previous point, and a change to an uptrend when a point is higher than the previous point.

 

I will upload a new version soon with the comments, and also with a new option to allow determining the moving average price by something other than Close. e.g. (High+Low+Close)/3. This was a feature I neglected to add.

I have dowloaded the latest version of the indicator and still cannot get the chart to print cadle stick chart as in the original example. When I toggle between OHLC and candlestick the OHLC is overlayed on the candlestick. It seems that the paintbar will only showup in OHLC format.

I also noticed that at the bottom section for volume in the original example there is a $I-Volume is there something I'm missing to get this to show as the example?

Can you post a screenshot of your desktop? The indicator is working properly for me.

Latest version with new inputs plus comments.

 

Price = Calculation of price to be used to determine trend. e.g. Close, or, (High+Low+Close)/3), etc.

 

PriceLength = Number of price bars to look back to determine trend.

 

VolLength = Number of volume bars to look back to determine volume trend.

 

ShowTrend = Paint the bars showing the trend. If false, up bars are green, down are red.

 

ShowVolume = Paint the bars show showing volume density. If false, all bars are the same density.

Rob,

 

No still only paints OHLC - works great but no go on the candles - I also tried the default Volume Gradient and it does the same thing. I will look to upgrade to ver 8.2 over the weekend and not migrate existing data. Fresh install and I will manually move everything back in. Hopefully that will fix it. What version are you on hence it works for you?

Doesn't work for me either and I'm on TS82. v3863. Screenshot attached of candle vs. bar chart.

 

Any ideas GCB?

 

keymoo,

 

That is so weird. I have no idea right now. The function which does the work is NormGradientColor(), everything else about the indicator is pretty basic.

 

I can't debug it because it's not happening to me. All I can suggest is to call TS.

 

But try the TS supplied paintbar indicator called Volume Gradient. They'd hesitate to to support mine, but they have to support their own.

Rick,

 

Send me your email addresss. The forum won't let me upload a workspace.

GCB;

 

While VSA makes different assumptions about volume, I must say that this is a great idea. I commend you on your work. Would love to see more charts and then of course......trading ideas/set-ups that this tool brings about.

    • Date: 29th March 2024. GBPUSD Analysis: The Pound Trades Higher But For How Long? The global Stocks Markets are closed due to Easter Friday (Good Friday). The NASDAQ continued to follow the sideways trend while other indices again rose. The SNP500 reaches an all-time high, but the NASDAQ remains under pressure from Tesla, Meta and Apple. The Euro continues to trade lower against all major currencies including the US Dollar, Euro and Japanese Yen. The British Pound is the best performing currency during this morning’s Asian session. However, investors are largely fixing their attention on this afternoon’s Core PCE Price Index. GBPUSD – The Pound Trades Higher but For How Long? The GBPUSD is slightly higher than the day’s open and is primary due to the Pound’s strong performance. At the moment, the British Pound is increasing in value against all major currencies. However, the US Dollar Index is also trading 0.10% higher and for this reason there is a slight conflict here. If investors wish to avoid this conflict, the EURUSD is a better option. This is because, the Euro depreciating against the whole currency market avoiding the “tug-of-war” scenario. The GBPUSD is trading slightly lower than the 2-month’s average price and is trading at 49.10 on the RSI. For this reason, the price of the exchange is at a “neutral” level and is signalling neither a buy nor a sell. The day’s price action and future signals are possibly likely to be triggered by this afternoon’s Core PCE Price Index. Analysts expect the Core PCE Price Index to read 0.3% which is slightly lower than the previous month but will result in the annual figure remaining at 2.85%. The PCE rate is different to the inflation rate and the Fed aims for a rate between 1.5% to 2.00%. Therefore, even if the annual rate remains at 2.85%, as analysts expect, it would be too high for the Fed. If the rate increases, even if only slightly, the US Dollar can again renew bullish momentum and the stock market can come under pressure. This includes the SNP500. Investors are focused on the publication of data on the UK’s gross domestic product (GDP) for the last quarter of 2023: the quarterly figures decreased by 0.3%, and 0.2% over the past 12-months. This confirms the state of a shallow recession and the need for stimulation. The data, combined with a cooling labor market and a steady decline in inflation, increase the likelihood that the Bank of England will soon begin interest rate cuts. In the latest meeting the Bank of England representatives did not see any members vote for a hike. USA500 – The SNP500 Rises to New Highs, But Cannot Hold Onto Gains! The price of the SNP500 rises to an all-time high, before correcting 0.33% and ending the day slightly lower than the open price. Nonetheless, the index performs better than the NASDAQ which came under pressure from Tesla, Meta and Apple which hold a higher weight compared to the SNP500. For the SNP500, these 3 stocks hold a weight of 9.25%, whereas the 3 stocks make up 14.63% of the NASDAQ. The SNP500 is also supported by ExxonMobil’s gains due to higher energy prices. The market will remain closed on Friday due to Easter. However, the market will reopen on Monday for the US and investors can expect high volatility. Investors will also need to take into consideration how the PCE Price Index and the changed value of the US Dollar is likely to affect the stock market next week.
