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 auto trading. 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 the following order execution gatewayschances of delay are reduced.MultiCharts offers 2 modes of automated trading: FXCM, Interactive Brokers, Patsystems, Rithmic Trader, Trading Technologies, Synchronous and Zen-FireAsynchronous. The modes are fundamentally different. Here’s the overview of each mode.

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

In addition to The SA mode should work properly and the auto trading 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 Mode of Auto Trading (AA)== The asynchronous auto trading modes mode (AA) is the mode in which the trades are plotted on the chart when the order generation conditions are deployed met with no respect to the real order executions on the broker. In this aspect auto trading in MultiCharts. These two modes AA is more like backtesting with the only difference: the orders are profoundly differentactually sent to the broker. Select the The AA mode that better suits continues trading from the strategy on current backtesting position. As with the chart. Synchronous SA mode makes it is possible to show a [[Auto_Trading#Assign_the_Initial_Market_Position_at_the_Broker_Settings|assign the starting position on the chart ]] for auto trading, but this cannot guarantee that matches the actual filled [[Why_There_Is_Mismatch_On_Strategy_Positions_Tab|broker and strategy position. However there is no guarantee that mismatches]] won’t happen later in the order will get filledcourse of auto trading. When using One should not expect the Asynchronous mode, every order generated execution prices on the chart is filled, although to coincide with the actual order execution time and price can be different from prices on the broker because this mode is not synchronized with the time and price shown on broker as is suggested by the chartmode's name.
