After developing Once a strategyfor automated trading is [[Using_Studies_(PowerLanguage_Editor)#Creating_Signals|developed]], [[Understanding_Backtesting|backtested]] and [[Performing_Optimization|optimized]], the next step is to have the strategy it actually send the ordersto the [[Broker_Profiles_Overview|broker]]. The orders are submitted to the selected broker through the [[Auto_Trading#Select_Broker_Plug-in|auto trading broker plugin]] implemented in MultiCharts. As opposed to the purely brokerage programs MultiCharts automated has a capability of combining the [[Built-in_Data_Sources|data sources]] that are different from the desired broker during autotrading. This is realized through the [[Symbol_Mapping|Symbol Mapping]] functionality and provides additional possibilities and advantages for traders.Automated trading platform has two primary benefits: convenience and speed. A trader can automate let the strategy trade automatically without having to constantly monitor the strategy and enter the orders himself (though we don’t recommend leaving the strategy unattended at all!). Automated trading also allows for sending the orders much quicker compared to manual trading process . The orders are submitted automatically and seamlessly integrate with any the chances of delay are reduced.MultiCharts offers 2 modes of automated trading: Synchronous and Asynchronous. The modes are fundamentally different. Here’s the supported order execution infrastructures: [[Broker Profiles Overview]]overview of each mode.

Automated The synchronous auto trading has two primary benefits: convenience and speedmode (SA) is the mode in which the trades are only reflected on the chart after the orders have actually been executed on the broker. SA always starts trading from Flat as if there were no previous historical trading results. The trader can let his strategy trade automatically without having to constantly monitor is not recalculated on the start of autotrading. When it will be calculated depends on the strategy [[Chart_Resolution|chart resolution]] and enter the orders himself[[Signal_Settings#Intra-Bar_Order_Generation|Intra-Bar Order Generation]] (IOG) setting. Automated trading If there’s an open position on the broker one can also send tell the orders much quicker. Certain strategies require orders strategy to be sent as quickly as possible without delaycontinue trading from this position. With auto trading, the trader does not have See how to manually type the order into the gateway. The trades are submitted automatically and assign the chances of delay are reducedpostion [[Auto_Trading#Assign_the_Initial_Market_Position_at_the_Broker_Settings|here]].

In addition to The SA mode should work properly and the autotrading and broker positions should match if the obvious advantages of convenience, automated following aspects are avoided:* [[Trading_from_Multiple_Charts_on_One_Instrument|trading makes possible on one and the execution of highsame instrument/broker account from other charts]];* starting the trading from a non-frequency flat broker position;* trading strategies such as arbitrage, where the acceptable response same instrument in the broker platform at the same time for placing orders is too quick for manual ;* losing the connection to the broker at the moments of order entriesfillings/rejections.

Both, Synchronous and ==Asynchronous auto trading modes are deployed in MultiCharts. These two modes are profoundly different. Select the mode that better suits the strategy on the chart. Synchronous mode makes it possible to show a position on the chart that matches the actual filled position. However there is no guarantee that the order will get filled. When using the Asynchronous mode, not every order generated on the chart is filled and the actual execution time and price can be different from the time and price shown on the chart. Mode of Auto Trading (AA)==

<br>[[Category:AutoTrading]]=== Synchronous Mode for Auto Trading === The synchronous asynchronous auto trading mode (SAAA) is a the mode where entry/exit arrows in which the trades are plotted on the chart when the order generation conditions are met with no respect to the real order executions on the broker. In this aspect auto trading in AA is more like backtesting with the only after difference: the orders have been executed at are actually sent to the broker.  The synchronous auto AA mode continues trading mode ensures avoiding discrepancies between from the market current backtesting position on . As with the chart and SA mode it is possible to [[Auto_Trading#Assign_the_Initial_Market_Position_at_the_Broker_Settings|assign the market starting position at ]] for auto trading, but this cannot guarantee that the [[Why_There_Is_Mismatch_On_Strategy_Positions_Tab|broker. The following conditions must be met and strategy position mismatches]] won’t happen later in order for the synchronous course of auto trading . One should not expect the order execution prices on the chart to coincide with the order execution prices on the broker because this mode is not synchronized with the broker as is suggested by the mode to work properly: 's name.

=== Asynchronous Mode for Auto Trading === The asynchronous auto trading mode (AA) is the mode where entry/exit arrows are plotted on the chart when the price value meets the strategy conditions.  However, order execution by the broker is not guaranteed if the conversion of unexecuted limit/stop entry orders is disabled. It may cause a market position conflict between the chart and the broker.  Enabling order conversion guarantees that an order will be filled at the broker, although the executed order price value could be different from the order price plotted on the chart. <br>=== Comparison of Synchronous and Asynchronous Mode ===
