Candle Stick Indicator

[FX989231]

The attached indicator was developed by Alexis a few years ago. I use it to plot the oil or gold price below currency charts or sometimes plot another curency. The problem is that it only gives values to 2 decimal places.

Alexis (or some one who can solve this problem) can you please guide me in what code to add in order to get 4 decimal places on this indicator

Your help will be appreciated

Regards

Already did this once today, so no biggie.

It is still only plotting 2 decimals, any reason?

I also do not understand what the following mean:

// for RTH, eg, to convert, ES Z2 to ES Z2=2
var rootSymbol = vSymbol.substring(0,3);
if (rootSymbol == "ES " || rootSymbol == "NQ ")
if ( vSymbol.indexOf("=2") == -1 ) vSymbol += "=2";

Can you please explain so that I can understand?

At this time efs does not offer the option to increase the number of decimals in a plot.
The only solution currently available is to adjust the returned values using a multiplier (in the case of currencies for example use 1000 which is what I set as the default). The enclosed revision should approximate the result that you want

That section of code converts an ES my or NQ my symbol to its to its RTH equivalent by adding an =2 at the end of the symbol ie. ES my=2 or NQ my=2. FWIW it is not used in the context of that script

I just realized I set the default value for Factor at 100 and have replaced the attachment. You can download it again or just change the default value to 1000

Thank you it looks much better than before.

One more question:

When you export data using TOOLS> DATA EXPORT, is there a way of exporting the name of the symbol or indicator with the data?

At the moment it looks like this;

Alexis or anyone:

Can you explain why my solution worked for equities but not forex?

For the stock I plotted, if you don't specify 3 or more decimals, then it only plots to 2 decimal places.

But when you enter 3 or more it plots correctly.

Thanking You in Advance.

Actually it does not work for equities either if you try to increase the number of decimals beyond what the formula engine will itself display. If you look at the image you posted you will see that the last price is 0.0074 while the efs is displaying 0.007 even though it is set to 4 decimals.
Enclosed is another snapshot of your version of the efs together with the original version and as you can see both return the same exact number of decimals (even though the latter is not set to return any specific number of decimals)

I don't think the Data Export Tool has a way to include the symbol in its output.
However there is a workaround which is to add the symbol as a string in the returned array of the efs (see enclosed revision of the script). In this way the symbol will display in the Cursor Window and is also available to the Data Export Tool (see enclosed images)

Thanks for explaining, Alexis.

Candle stick, plot line instead

Can any one specify changes to thie clever candle stick indicator efs that will plot a price line, like at close or hcl/3 rather than the simulated candle sticks. Appreciate any guidance.
