that you are reassigning a variable that is already used elsewhere in the sourcecode. A list of keywords is provided in the appendix to help prevent this fromhappening.Let’s get to the heart of the ESB by scrolling down to the main trading loop. Youcan find it by looking for the comment block that says, ‘‘Main Trading Loop.’’ Theentire Main Trading Loop is shown below. This includes some of the code we havealready discussed and some code that you can simply ignore.’****************************************************************’**** Main Trading Loop ****’****************************************************************Do While i <= numRecordstradeDays = tradeDays + 1IncrementalProgress.Showi = i + 1’Dont touchsPercentage = (i / numRecords) * 100sStatus = "Checking " & i & " of " & numRecords &" paragraphs"IncrementalProgress.Increment sPercentage, sStatusintraDayTrdCnt = 0’Leave in.If barsLong <> 0 Then barsLong = barsLong + 1 ’Leave in.If barsShort <> 0 Then barsShort = barsShort + 1 ’Leave in.’****************************************************************’**** This is a good place to put all of your function calls ****’**** and system calculations. ****’****************************************************************Call BollingerBand(myClose, 60, 2, avg, upBand, dnBand, i, 1)simpleAvg = Average(myClose, 10, i, 1)rsiVal = RSI(myClose, 14, i, 1)Call Stochastic(3, 4, 7, stoK, stoD, slowD, i, 1)’****************************************************************’**** Put All Of Your Orders Here ****’****************************************************************prevMarketPosition = marketPositionIf marketPosition <> 1 ThenCall Trade(Buy, "BB-Buy", upBand, stp, i)End IfIf marketPosition <> -1 ThenCall Trade(Sell, "BB-Short", dnBand, stp, i)159USING MICROSOFT EXCEL TO BACKTEST YOUR ALGORITHMwww.rasabourse.com

Don’t worryabout any of the source code above the Main Trading Loop comment block:’****************************************************************’**** This is a good place to put all of your function calls ****’**** and system calculations. ****’****************************************************************All of your programming will take place below these comments. For illustrationpurposes, I immediately call four indicator functions/subroutines.Call BollingerBand(myClose, 60, 2, avg, upBand, dnBand, i, 1)simpleAvg = Average(myClose, 10, i, 1)rsiVal = RSI(myClose, 14, i, 1)Call Stochastic(3, 4, 7, stoK, stoD, slowD, i, 1)This algorithm will just use the values modified in the BollingerBand subroutine:avg, upBand, dnBand. Let’s look at the other function calls in the program:■Average. This function returns a moving average value for the past 10 days. Itsfirst argument is the data array that is to be averaged, and the second argumentwww.rasabourse.com
