### Understand order_types
|
||||
|
||||
`order_types` contains a dict mapping order-types to market-types as well as stoploss on or off exchange type. This allows to buy using limit orders, sell using limit-orders, and create stoploss orders using market. It also allows to set the stoploss "on exchange" which means stoploss order would be placed immediately once the buy order is fulfilled.
|
||||
`order_types` contains a dict mapping order-types to market-types as well as stoploss on or off exchange type and stoploss on exchange update interval in seconds. This allows to buy using limit orders, sell using limit-orders, and create stoploss orders using market. It also allows to set the stoploss "on exchange" which means stoploss order would be placed immediately once the buy order is fulfilled. In case stoploss on exchange and `trailing_stop` are both set, then the bot will use `stoploss_on_exchange_interval` to check it periodically and update it if necessary (e.x. in case of trailing stoploss).
|
||||
This can be set in the configuration or in the strategy. Configuration overwrites strategy configurations.
|
||||
|
||||
If this is configured, all 4 values (`"buy"`, `"sell"`, `"stoploss"`, `"stoploss_on_exchange"`) need to be present, otherwise the bot warn about it and will fail to start.

Not all exchanges support "market" orders.

The following message will be shown if your exchange does not support market orders: `"Exchange <yourexchange> does not support market orders."`

!!! Note
|

stoploss on exchange interval is not mandatory. Do not change it's value if you are unsure of what you are doing. For more information about how stoploss works please read [the stoploss documentation](stoploss.md).

### Understand order_time_in_force
|
||||
`order_time_in_force` defines the policy by which the order is executed on the exchange. Three commonly used time in force are:<br/>

At this stage the bot contains the following stoploss support modes:

|

2. trailing stop loss, defined in the configuration

|

All stoploss properties can be configured in eihter Strategy or configuration. Configuration values override strategy values.
|
||||
All stoploss properties can be configured in either Strategy or configuration. Configuration values override strategy values.
|
||||
|
||||
Those stoploss modes can be *on exchange* or *off exchange*. If the stoploss is *on exchange* it means a stoploss limit order is placed on the exchange immediately after buy order happens successfuly. This will protect you against sudden crashes in market as the order will be in the queue immediately and if market goes down then the order has more chance of being fulfilled.
|
||||
|
||||
In case of stoploss on exchange there is another parameter called `stoploss_on_exchange_interval`. This configures the interval in seconds at which the bot will check the stoploss and update it if necessary. As an example in case of trailing stoploss if the order is on the exchange and the market is going up then the bot automatically cancels the previous stoploss order and put a new one with a stop value higher than previous one. It is clear that the bot cannot do it every 5 seconds otherwise it gets banned. So this parameter will tell the bot how often it should update the stoploss order. The default value is 60 (1 minute).
|
||||
|
||||
!!! Note
|
||||
Stoploss on exchange is only supported for Binance as of now.
