Seasonal Trend Indicator (STI)

Dear KXC

I notice there were no replies to your request and the probable reason is that your request is to code a Pandora's Box of possibilities.

I will not code what you want but I will show you a possible way for you to resolve a bit of what you want.

The reason I think this is a practical solution is that I recently tried to code a Murrey Math Indicator. To some extent the start date for Murrey Math is a bit like a seasonal indicator, T H Murrey starts each year on the Harvest Moon. Sounds good but he lives in North America. The Harvest Moon in Australia falls on a date about 6 months later in the Calender year. Each year the Harvest moon changes within a range, so it is not like Christmas day is 25 December each year. So getting a seasonal date right is a moveable feast, and if you want to go back 10 years, it probably ain't going to happen using a standard Forum indicator.

Gann starts many of his approaches using various equinoxe dates and depending where you are in the world his dates may not be the same at your centre of gravity dates.

The solution I came up which is probably usefule for the last year of trading will be shown below.

I am heavily dependent on some really very smart code by Jose Silva who used to write a lot of very good indicators on Metastock Forums and on his own Metastock Tools website.   Some of them are seasonal indicators.

I converted to Bullcharts some years back one of Jose's indicators showing the Full Moon, Half Moon and quarter Moon and they are shown at the top of two charts below.

They are based on Calender days, hence there is a squiggle in the trading day chart indicator lines.   (If you go into Bullcharts and the Format menu, select and Time Axis and untick the boxes for Hidden weekends, Public holidays and After Hours you will see that the indicator becomes a straight line as it is then showing on a calendar not trading day chart.

Step 1 is put on the Moon indicator. The ASX is 10 hours from Greenwich meridian so that parameter should show 10   Then you get the dates of the moon phases. My conversion of Jose Code with his copyright is shown further below.

Step 2 is set up you moveable indicator adapting into your indicator code the top two Bullscript lines I have shown in Chart I. (I also pick this up from something Maximo did on this forum for a stop loss indicator, so again I am beholden to him.

This ability to easily move an indicator backwards and forwards on a chart means you can easily find the start of your relevant season on the chart if the season starts on a full moon which many commodity seasons probably do, or if you know the particular date when the chart is put into Calender day mode.

So for the example in chart 1, I started the indicator on the Full Moon of 17 July 2014.

But assume you know that the particular season you want started on the full Moon 14 February 2014, then click on the indicator heading or indicator chart and a verticle line will appear which you grab with your mouse and drag the indicator across the chart to the day before 17 Feb 2014 and you will then have the indicator showing from the start of the season you want.

I will post the two charts below then the Adaptation of the Moon indicator code.
