• symbols - number of symbols from the symbols list to run simultaneously.(Multi-Symbol mode only works live. MT4 Tester can not do multi-symbols.)
• sym_iteration - If true will run a single symbol per frame. If true "symbols" will be the variable of which symbol to run instead of how many symbols to run. Used to optimize "symbols" in order to obtain a separate frame for each symbol.
• symbol0..symbol30 - symbols list
• scndrySadj - All secondary symbols will have their risk multiplied by this factor.
• timeframes - number of timeframes from the timeframes list to run on simultaneously.
• timeframe0..timeframe5 - timeframes list
• scndryTadj - All secondary time-frames will have their risk multiplied by this factor.
• FREQUENCY - number of seconds to wait in between main program calls
• magic - Magic Number (Now plays nice with other EA and other instances of itself on the same symbol as long as magic is unique)
• CheckMargin - Check margin before placing and order. You may turn off to increase performance in Tester.
• slippage - maximum allowable slippage (if broker allows such a setting.)
• maxspread - maximum spread allowed before it triggers safety mode and closes all pending orders temporarily.
• Lots - risk expressed in percent.
• stoploss - stop loss expressed in either ATR or Bollinger Band Percent  (depending on the "factor1" setting, see below.)
• takeprofit - take profit expressed in either ATR or Bollinger Band Percent as defined bellow.
• trailstop - trailing stop loss expressed in either ATR or Bolinger Band Percent (depending on the "factor1" setting, see below.)
• trailpadding - padding of the trailing stop loss expressed in either ATR or Bollinger Band Percent (depending on the "factor1" setting, see below.)
• BRNTrailadj - adjuster used in the calculation of the frequency of the "big round numbers" A higher number means less frequent (further apart) big round numbers. This is a complex algorithm which includes volatility readings but is optimizable across markets.
• Chanlength - length of channel expressed in bars.
• Chanwidth - width of channel expressed in either ATR or Bollinger Band Percent depending on the "factor2" setting (see below.)
• chancore - Channel core expressed in either ATR or Bollinger Band Percent depending on the "factor2" setting (see below.)
• pad - pending order padding expressed in either ATR or Bollinger Band Percent depending on the "factor1" setting (see below.)
• dchanmaxorderage - maximum order age of pending orders expressed in bars.
• dchanmaxposage - maximum position age of open position expressed in bars.
• lotchngsense - minimum percent change of the lotsize before an order replace sequence occurs.
• tpchngsense - minimum percent change of TP distance before an order modify or replace sequence is triggered. (With the exception of a shrinking channel. In case the channel gets tighter/smaller, the order will always adjust)
• maxadjDistance - expressed in either ATR or Bollinger Band Percent depending on the "factor1"  setting (see below.) The market price must be within this price range for an order replace or order modify sequence to take place.
• F1type - Factor 1 definition. Can be set to either "bbF" (percent of bolinger band 1) or "atrF" (ATR 1). This is the measurement that the SL, trailing SL and pad are expressed in.
• F2type - Factor 2 definition. Can be set to either  "bbF" (percent of bolinger band 2) or "atrF" (ATR 2). This is the measurement that the channel width is expressed in.
• Fbars1 - bars for the factor 1 calculation.
• Fbars2 - bars for the factor 2 calculation.
• bbd1 - Bollinger Band 1 deviation setting.
• bbd2 - Bollinger Band 2 deviation setting.
• FnumTP - whether to us factor 1 or factor 2 to express the take profit measurement.
• Cspreadmode - custom spread mode. Can either be set to "csADD" to add points to existing spread to simulate a wider spread or "csMIN" to be a static minimum spread. Balance is adjusted with the withdrawal function of Tester to replicate this larger spread. Use it to factor in additional commission and slippage to make sure your strategy/settings are robust.
• CustomSpread - Custom spread expressed in points.
• TesterMinTrades - Minimum trades used to calculate custom score of tester
• MaxDchanWrat - maximum width to length ratio of the channel. Will error on init with an incorrect parameters message if this ratio is higher. Used to restrict the optimizer to appropriate width vs height ratios. 
• MinDchanWrat - minimum width to length ratio of the channel. Will error on init with incorrect parameters message if this ratio is lower. Used to restrict the optimizer to appropriate width vs height ratios. 
• randFmode - Can be set to "scndtf" which will apply a change to the factors of all timeframes other than the timframe0. (Can be used to force a jiggle test on each frame if used in combination with a multi-timeframe optimization where all timeframe0..timeframe5 are the same. see below) Can be set to "all" which will change the factors of all timeframes including the timeframe0. Can be set to "off" as well.
• distributionmode - can be set to "randD" which will make any factor changes random for a Monte Carlo effect or can be set to "evenD" which will make any factor changes evenly distributed.(see below)
• RandPercent - Maximum percent of change applied to the factors when rand mode is on. This effects both randD mode and evenD mode. (see below for examples)

Optimization

Please read all MetaTrader 5 documents regarding curve fitting and backtesting. Always check across data feeds, pairs and time-frames. Please check the comments area for more tips on optimizations.

Sample Anti-Curve-Fitting optimization techniques. (These techniques take much, much longer and do not yield the impossibly nice looking equity curves of a curve fitted set but do yield individual back tests highly correlated with their out of sample forward tests.. Please test for yourself.):

• Built in 4x Jiggle Test 
  Description - Used during optimizations for robustness. There will be 4 additional jiggled 5 minute runs for each frame where the factors (effecting channel length, width, core, SL and TP) will be +6.25%, +12.5%, -12.5%, -6.25% making sure a wide range of similar settings are profitable during optimization. 
  Instructions - Set timeframes to 5. Set timeframe0..timeframe4 to "5 minutes". Set randFmode to "scndtf". set distributionmode to "evenD". Set RandPercent to 25. ~Optimize~. set timeframes to 1 and then "run once" to show back and or forward test or to use in live demo test. 
• Built in 5x Time Dilation Test
  Description - Used during optimization for robustness. There will be 5 additional secondary timeframes.
  Instructions - Set timeframes to 6. Set timeframe0 to the primary timeframe ("5 minutes" for example). Set timeframe1..timeframe5 to the secondary timeframes ("3 minutes", "4 minutes", "6 minutes", "10 minutes" and "12 minutes" for example) . ~Optimize~. set timeframes to 1 and then do a "run once" to show back test and or forward test or to use in live demo testing.
• Monte Carlo 10x
  Description - 10 randomly adjusted frames (+/- 12.5%) for verifying robustness of settings after optimization is complete.
  Instructions - Set randFmode to "all". Set distributionmode to "randD". Set RandPercent to 25. Optimize FREQUENCY only (333 to 343 step 1). View Optimization results to verify robustness.

Sample usage of Factor1 and Factor2 combos:

• Bollinger Band Percent for expression of TP, SL, pad and trailing SL
  Description - TP, pad, SL and trailing SL will be expressed in Bollinger Band Percent instead of ATR. channelwidth will be expressed in ATR. TP will be expressed in short term Bollinger Band Percent (BB1).
  Instructions - Set F1Type to "bbF". Set F2type to "atrF". Set FnumTP to "f1".
• Use ATR to express TP, SL, pad, trailing SL and channelwidth
  Description - all settings are expressed in ATR. TP is expressed in long term ATR (ATR2).
  Instructions - Set F1type to "atrF". Set F2type to "atrF" set FnumTP to "f2".
