Changes

Though the these 2 pieces of software are similar in many aspects , and the scripting languages (EasyLanguage vs. PowerLanguage) are 99% compatible, strategy/study calculation results may still in fact differ.<br>To have the same results, make sure the following requirements are met.:

Make sure the data on the charts is the same both in MC and in TS:# Same The same data source ([[TradeStation]]) should be used to feed charts in MC and in TS software. Comparing strategy/study calculation results on charts with data from different data providers is irrelevant. # Same The same symbol should be plotted on charts in MC and TS software. It means the symbol should have exactly the same name and exchange.# Same The same chart type should be selected for both charts in MC and in TS. It is irrelevant 's impractical to compare results based on different chart types even within 1 piece of software.# Same The same [[Chart Resolution]] should be set for both charts. It is irrelevant to compare results based on different chart resolutions even within 1 piece of software.# Since TradeStation software doesn’t does not allow using asks and bids as a data series on a chart, only trades should be selected in MultiCharts in [[Quote Field]].# Same The same [[Sessions]] should be applied for the symbols in both pieces of software. It is important to understand that having “default” in the session field for a chart in MC doesn’t does not mean the same sessions are set for a chart in TS. Please read [[What Affects Chart Timestamps|this article]] to learn more.# If the strategy/study references volume data for its calculation, the same option should be selected in the Build Volume On field in the chart settings for both in TS and MC.# Same The same time interval should be specified in the [[Data Range]] setting for the charts in TS and MC.# If the strategy/study references date and time for its calculation, the same option should be selected in the [[Time Zone]] field in the chart settings both in TS and MC.# Even if the data range and session settings are the same, the actual number of bars on the chart in a MC vs. a chart in TS may still differ (for example due to [[Setting Holidays|Holiday List]]). This difference may lead to different strategy/study calculation results. It is necessary to make the actual number of bars on the charts either the same or as close to each other as possible.<br><div style="background-color: #E3FBE5;">'''Note''': In MultiCharts you can see last bar number in [[Using Pointers#Understanding Hint Modes|Hint]] or [[Data Window]] if you put your cursor on the last bar on the chart. In TradeStation this is not available out of boxright away, but there is an easy way to find it out:<br>Make a '''right-click on chart in TS''' -> '''Insert Analysis Technique…''' -> '''Indicators''' tab -> Select '''Custom 1 Line''' indicator -> '''Ok''' -> Insert the following as the '''Formula''' input '''currentbar+maxbarsback''' -> '''Ok'''. You will see the indicator on the subchart showing ''the actual number of bars''.# The price formats on the chart should be the same. It This means that the number of digits in the integer part of the price scale and number of digits in the decimal part of the [[Price Scale]] should be the same in a MC chart and in a TS chart.

# Since EasyLanguage(TS) and PowerLanguage(MC) are almost the same but not 100%, the script may required some syntax adjustment, but the logic of the script should be the same in both pieces of software.

# [[How Signals are Calculated|IntraBar Order Generation and Bar Magnifier features for signals (strategies) in MultiCharts work slightly different]] from their analogues counterparts in TradeStation. One should not expect identical results if any of these 2 features are used.# [[Limit Order Execution Assumptions|Limit Order Fill Assumptions]] should also be also configured identically for the charts in both platforms. TradeStation has additional options for this feature that are not supported in MultiCharts.# Such The feature as ''Market Order Fill Assumption'' (Backtesting tab of Strategy Properties) is not implemented in MultiCharts. It should be disabled in TradeStation.# [[Commission Rules|Commissions]], [[Strategy Properties#Setting Costs/Capitalization|Slippage]] (that doesn’t does not affect limit and stop limit orders in MC), [[Strategy Properties#Setting Costs/Capitalization|Initial Capital]], [[Strategy Properties#Setting Costs/Capitalization|Interest Rate]], [[Strategy Properties#Setting Position Limits|Position Limits (pyramiding)]], [[Strategy Properties#Setting Position Limits|Maximum Shares/Contracts/Units per Position]], [[Strategy Properties#Setting Trade Size|Trade Size]] and especially [[Strategy Properties#Setting Maximum Bars Back|Maximum Number of Bars Study Will Reference (MaxBarsBack)]] should be configured identically in MultiCharts and TradeStation.
