It is a simplest strategy that buys and sells on every bar. Strategy based around Open-Close Crossovers, which can be tuned for smooth trend trading, or with a little care even work for choppy waters.
It means that as soon as an order from level 1 is filled, the orders from level 2 are not cancelled, they stay active. Every command placing an order has ID string value — unique order identifier. If an order with same ID is already placed but not yet filled , current command modifies the existing order.
If modification is not possible conversion from buy to sell , the old order is cancelled, the new order is placed. To cancel a specific order by its ID the command strategy. To cancel all pending orders the command strategy. Strategy orders are placed as soon as their conditions are satisfied and command is called in code. It means that if a market order is generated at close of current bar, it is filled at open oif next bar. Conditions for order placement when , pyramiding , strategy.
If all conditions are satisfied, the order is placed. If any condition is not satisfied, the order is not placed. It is important to cancel price orders limit, stop and stop-limit orders. Even though pyramiding is disabled, these both orders are filled in backtesting, because when they are generated there is no open long market position. Both orders are placed and when price satisfies order execution, they both get executed.
It is recommended to to put the orders in 1 OCA group by means of strategy. Here is the modified code:. If, for some reason, order placing conditions are not met when executing the command, the entry order will not be placed. For example, if pyramiding settings are set to 2, existing position already contains two entries and the strategy tries to place a third one, it will not be placed. Entry conditions are evaluated at the order generation stage and not at the execution stage.
Therefore, if you submit two price type entries with pyramiding disabled, once one of them is executed the other will not be cancelled automatically. To avoid issues we recommend using OCA-Cancel groups for entries so when one entry order is filled the others are cancelled. The same is true for price type exits - orders will be placed once their conditions are met i.
If you apply this example to a chart, you can see that the exit order has been filled despite the fact that it had been generated only once before the entry order to be closed was placed.
However, the next entry was not closed before the end of the calculation as the exit command has already been triggered. Despite it is possible to exit from a specific entry in code, when orders are shown in the List of Trades on StrategyTester tab, they all are linked according FIFO first in, first out rule.
If an entry order ID is not specified for an exit order in code, the exit order closes the first entry order that opened market position. The code given above places 2 orders sequentially: Exit order is placed only after entry orders have been filled. If you apply the code to a chart, you will see that each entry order is closed by exit order, though we did not specify entry order ID to close in this line: It means that the no matter what entry order you specify for your strategy to close, the broker emulator will still close the the first one according to FIFO rule.
It works the same way when trading with through broker. You may think that this is a reverse strategy since pyramiding is not allowed, but in fact both order will get filled because they are market order, what means they are to be executed immediately at current price.
The same would happen if these were price orders with same or similar prices. Strategy places all orders which are allowed according to market position, etc. The strategy places all orders that do not contradict the rules in our case market position is flat, therefore any entry order can be filled. At each tick calculation, firstly all orders with the satisfied conditions are executed and only then the orders from the group where an order was executed are cancelled.
Every group has its own unique id the same way as the orders have. If two groups have the same id, but different type, they will be considered different groups. It is not easy to create a universal profitable strategy. Usually, strategies are created for certain market patterns and can produce uncontrollable losses when applied to other data. Therefore stopping auto trading in time should things go bad is a serious issue.
There is a special group of strategy commands to manage risks. They all start with the strategy. You can combine any number of risks in any combination within one strategy.
There is no way to disable any risk rule in runtime from script. Regardless of where in the script the risk rule is located it will always be applied unless the line with the rule is deleted and the script is recompiled. If on the next calculation any of the rules is triggered, no orders will be sent. Therefore if a strategy has several rules of the same type with different parameters, it will stop calculating when the rule with the most strict parameters is triggered.
When a strategy is stopped all unexecuted orders are cancelled and then a market order is sent to close the position if it is not flat. The position will be closed and trading will be stopped until the end of every trading session after two orders are executed within this session as the second rule is triggered earlier and is valid until the end of the trading session.
