Can you show me an example on how to build an indicator?
Here is an example, to show you how to build a simple indicator, to find out stock "its closing price is in 14 days highest". First, we will draft out our equation to Real Time Stock's Last Price >= Maximum from 14 days Stock's Last Price From the equation, we know that we need the following components :
- Real time stock information
- Relative stock history
What is the best way for me to share my indicator with friends?
- Right click on the indicator name and select Export....
- A zip file will be saved. Email the zip file to your friend.
- You friend might install it, by clicking on Install..., and select Install from local file.
How can I specific "N days back 14 days moving average"?
There is a skipDay field in Stock relative history information, where you may specific N days back. For instance, you would like to know 1 week ago 14 days moving average. You may assign 7 in skipDay, to indicate 1 week ago.
I would like to perform MACD scanning.
We implement MACD feature in both Stock relative history information and Stock history information. We are using 26-days slow period, and 12-days fast period.
- MACD : (12-day EMA - 26-day EMA)
- MACDSignal : N-day EMA of MACD Line
- MACDHist : MACD Line - Signal Line
