Both files contain the exact same set of Open High Low Close data. The formula based version should be easier to understand and serves as a way to verify that the VBA code that I wrote is correct. Both methods give the same result for both %k and %D.  The major benefit of using VBA is that the parameters for Stochastics can be easily changed from the input boxes. In addition the VBA method shows only the final result rather than take up five columns.

1. Disable Auto recover by selecting Tools>Options and selecting the “Save” tab. Uncheck “Save AutoRecover info every:”.  Instead make it a practice to always save backups of your trading files anytime you make changes.
2. Once your file is complete and you are ready to trade, disable error checking by selecting Tools>Options and selecting the “error checking” tab. Uncheck “Enable background error checking”.
3. Disable Macro Security, by selecting Tools>Macro>Security and setting it to low. If you are going to download excel files off the internet from untrusted sources, you will want to temporarily re enable macro security.
4. As previously posted, I would not suggest using Vista/2007 unless you have a newer computer with extremely fast processor.

MACD example in excel.

This post answers the following question.

“I have recently been trying to chart historical data in Excel in a bar chart format and found the “canned” graph allows only for high, low, and close, but not the open.  Do you have a simple way to add the open tick to a bar chart in Excel?”

There are four types of stock charts included in excel.

High Low Close

Open High Low Close

Volume High Low Close

Volume Open High Low Close

Select the Open High Low Close option.

If you want to also plot volume which I suspect may be the case, I always just used the Open High Low close chart then add in the volume as a new bar chart on the stock chart. To do this:

first setup your stock chart with open high low close. It should look something like this.

Next

click on the outer edge of the chart so that it is highlighted, click on “chart” from the menu bar and select “add data”. Select the volume column as your data.

Now your chart will look messed up because volume is plotted on the primary axis (along with price).

To change this just right click on the volume bar series (on the chart itself) and select “format data series”. next click on the “axis tab” and change to “secondary axis”. Next you may want to change the secondary axis scale so that volume stays way down below price. Once that is done your chart should look something like this.

Sub TWITTER()
Dim symbol As String
Dim Price As String
Dim xml, Username, Password, tweet
Set xml = CreateObject(“MSXML2.XMLHTTP”)
‘change this to your username in quotes
Username = “yourusername”
‘change this to your password in quotes
Password = “yourpassword”
‘let the symbol variable have the symbol name from your excel sheet
symbol = Workbooks(“yourworkbook.xls”).Worksheets(“yoursheetname”).Range(“a1 or your range”)
‘let the Price variable have the symbol name from your excel sheet
Price = Workbooks(“yourworkbook.xls”).Worksheets(“yoursheetname”).Range(“a2 or your range”)
‘contruct the “tweet” this would create “Just bought a gazillion shares of (whatever $SYMBOL you have in A1) @ (whatever price you have in A2)
tweet = “Just bought a gazillion shares of ” & “$” & symbol & ” @ ” & Price
‘post the tweet
xml.Open “POST”, “http://” & Username & “:” & Password & “@twitter.com/statuses/update.xml?status=” & tweet, False
xml.setRequestHeader “Content-Type”, “content=text/html; charset=iso-8859-1″

If added to an existing excel trading system it may be best to set this to run 20 seconds or so after your actual trade is sent to avoid any interference which can be done as follows

Here is a short tutorial and an example file showing how to add a simple moving average to a stock chart. I am going to use the Simulator.xls as and example. It should be noted that all the unused columns on the BarData sheet (currently K-IV) of the simulator can be used to add indicators of your choice.

Trick number one. the =NA() trick

To plot a simple moving average (SMA), the formula is =AVERAGE(E132:E150)

So that would go in R150 on BarData Sheet.

There is a problem though. Excel will try to plot something when there is not enough data to average or even when there is an error. Here is an example of a chart we are trying to avoid.

The keep the chart clean, I want to generate the error NA# whenever I do not want anything plotted.

so to keep things looking right, change the formula in R150 to =IF(ISBLANK(E132),NA(),AVERAGE(E132:E150))

which means:

“If there is not enough data for this simple moving average, then give me NA# (so excel does not plot anything) otherwise just calculate the average.”

Next just drag and copy this formula from R150 up to R19 (the first cell where it is possible to have enought data to calculate the average!)

Now all that is left is to add this moving average to the chart. It’s surprisingly tricky though.

1. Right click on the chart and select “source data”

the following screen comes up. Click on “add” and fill it in as follows. (make sure there are some numbers in column R)

2. Select OK and take a look at the chart. Things should look funny on the chart now. Don’t worry about it, just find the data series “indicator”. It should be somewhere on the chart. In my case it plotted this price moving average on the secondary axis which is volume!

Hover your mouse around the volume series looking for “indicator”. Right click on the “indicator” series and change it to primary axis from secondary axis (which will be hidden somewhere down in the volume bars if it’s on the secondary axis. It can be hard to find/click on, if it is you may want to zoom in)

Now “indicator” should be plotted up there with price, but now the price chart will be all messed up!!!!!! (see how the first bar is missing parts!)

Next you once again need to hover your mouse around the price series looking for “indicator” when indicator is visible, right click on it and select “chart type”.

The following screen comes up and just select XY (Scatter) as shown and press OK.

Now the chart will look normal again.

The last step is to properly format this scatter chart to look like a line. For the last time find the “indicator” series on the chart and right click on it. This time select “format data series” and set it as follows.

Select “OK” and the resulting indicator should like like this.

One final tip.

Use google! If you are wanting to add a stochastic indicator for example, but don’t know how to calculate it. Try the following search:

stochastic filetype:xls

This will return tons of Excel files described with the word stochastic. There is a good chance that you will find a nice example there. If you have no luck, next you should search investopedia.com, which often explains the calculations.
