New Additions to Traders Edge Systems

Over the weekend we did a significant clean up job of our main website, Traders Edge Systems.

Some of the updates include:

• fixed broken links and fixed minor javascript issues
• made Stocks and Commodities magazine Traders Tips more accessible and organized
• flattened navigation links and buttons for easy access to Traders Tips and indicators
• made About Us and Contact pages cleaner, shorter, with only the essential

We've been doing a number of programming consulting gigs for Tradestation in the past few months. If you need something coded like an indicator or system in Tradestation, we can certainly assist you with our services.

You get all of the code (clean and organized code might I add) in your own ELD file for easy importation into Tradestation. We also can create pre-setup workspaces, desktops complete with charts and indicators already applied if you are unfamiliar with Tradestation.

Oanda: Great Forex Broker

Recently I've been dabbling with and learning the ins and outs of the Forex market. Finding a good broker / market maker in Forex seems to be one of the most difficult things. However, I've found one market maker that many people use who is reputable, cheap, and technologically more advanced than its competitors: Oanda. Its really worth checking out as they have a free unlimited "game" or practice account.

Ultimately we would like to automate some of our systems developed for Forex with Oanda's API but we're definitely not there yet.

Algorithm to Find Maximum Equity in an Array

Recently I've been working on learning Visual Basic .NET and applying it to writing some simple and some not-so-simple trading systems.

It took me a while to figure it out since I'm a little new to using For..Next and Do..Until/While loops in code but here's the way to find the current maximum equity if you have an array with equity values stored in each array cell:

For i as Integer = 0 to numberOfTrades - 1
If i = 0 Then ' no drawdown (obviously) before 1st trade is taken
maximumEquity = savedEquityArray(i)
Else ' for all other trades besides the first one
maximumEquity = savedEquityArray(i)
Do
If maximumEquity >= savedEquityArray(i - k) Then
maximumEquity = maximumEquity
Else
maximumEquity = savedEquityArray(i - k)
End If
Loop Until i - k = 0
End If
Next i

Then if you wanted to compute the drawdown up to that point you could say:

drawdown = Math.Round(((savedEquityArray(i) / maximumEquity) - 1) * 100, 2, MidpointRounding.AwayFromZero)
