I am sure there is a very simple solution to this. Can i Copy a symbol say XYZ existing in the Quotes or any other database as "XYZCopy" along with the prices etc so as to try out "Splits" etc on the copied Symbol. i earlier tried a split and probably because of entering wrong ratio I lostthe particular symbol data and had to reload the entire historical data. Also woul Split = Bonus Shares as well as Split Shares for charting purposes
Thank You
Raju

To make a copy of a symbol you should create a global script.

- Select Tools -> Script Editor
- Create a new file then paste the following code:

Chart chart = Charts.GetSelectedChart();
if(chart != null)
{
string newsymbol = chart.SymbolName + "_Copy";
HistoricalQuotes data = Quotes.GetHistoricalQuotes(chart.SymbolName);
Symbols.AddSymbol(newsymbol);
data.Symbol = newsymbol;
data.OpenInterest = new double[data.Close.Length];
Quotes.SaveHistoricalQuotes(data);
}



- The script will detect the active chart symbol and create a copy of this symbol (SymbolName_Copy)
- To add this script to the bookmark panel:
-> Right click on that panel (under the drawing tool buttons)
-> Select "Script" then click on "OK"
-> Select the file you have previously created

Now, in order to create a copy of a symbol, simply double-click on that bookmark icon.

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
