Hi John,

I purchased the DVD seminar and was wondering if you could provide the EL Code for your examples?

I know it only takes about 10 minutes to enter the code, but I attempted to create the indicator listed below from Slide #43 (Titled: Trend Following System--Tradestation Code) but it did not compile. And I want to ensure that I do not enter any potential typos which may have inadvertantly made it into the presentation.

Thanks very much,
Ron Wanat

****************************** BEGIN CODE *********
Variables: signal(0);

if BB_pctb > 0.8 and BB_MFI(10) > 80 Then begin
signal=1;
Alert("Confirmed Strength");
end
else
if BB_pctb < 0.2 and BB_MFI(10) < 20 Then begin
signal=-1;
Alert("Confirmed Weekness");
end
else
signal=0;
Plot1(signal, "BB-Strength");

The indicator, MFI, the Money Flow Index, in this code requires volume.
As volume is not reported in the forex markets, this code will not work for forex. To get it to work for other markets, you need to write the %b and MFI indicators that are referenced in your example and then it will compile.

MFI can work on Tradestation, Esignal and Metatrader4 as they all display 'tick' volume (number of trades per bar) for Forex. I am not familiar with Tradestation syntax, it is probably a typo such as a capital letter in the wrong place.

Then in order to get it to work you need to the two functions that the routine calls, BB_pctb and BB_MFI(10). MFI is probably already available on your TS, so just rename its call to your local MFI function name. Then enter the code for BB_pctb. Below is an example. Finally, change are the upper and lower band function calls, BBTK_upperBB and BBTK_lowerBB, to whatever the corresponding Bollinger Band function calls are on your system ands away you go.
