There are 2 possible reasons why an order is not placed at broker:
# The order was '''rejected''' either by MultiCharts, or by broker (in most cases you can find the reason of rejection on Logs tab of Order and Position Tracker (see [[Order and Position Tracker|Logs Tab]])
# The order was '''cancelled''' from script. According to EasyLanaguagelogic of EasyLanguage/PowerPowerLanguage, an order will be maintained as long as the conditions for its generation are met on each calculation. Once a condition is not met, it will be cancelled.
