Create an Order
Nonce is not required in authentication’s payload if client_order_id is provided.
limit_post_only orders are limit orders that are only accepted if they do not immediately execute. limit_post _only orders never take liquidity.
limit_post_only order will not match with pre-existing orders. If your order would cause a match with a pre-existing order, your limit_post_only order will be cancelled.
limit_post_only order ensures that you pay the maker and not the taker fee.
Available leverage may be limited based on position and/or jurisdiction.
For spot trading (leverage_level=1), the funding_currency, if specified, has to equal to the product's quoted currency, for example to create an order in product BTCJPY, the funding currency has to be JPY. 
For market_with_range:
price:
if order is buy: this order swipes out sell price ladders that has price lower than its price. If this action (partial order execution) bumps market ask price higher than its price, remaining unfulfilled quantity cancelled.
if order is sell: this order swipes out buy price ladders that has price higher than its price. If this action (partial order execution) bumps market ask price lower than its price, remaining unfulfilled quantity cancelled.
price_range: 
if order is buy: get the current market ask, + the price_range, then we have price and apply above logic.
if order is sell: get the current market bid, - the price_range.

CFD/Infinity Orders Additional Body Parameters
Parameters
Optional
Description
leverage_level
No
Valid levels: 2, 4, 5, 10, 25, 50, 100. Failure to supply these will result in an execution of spot order with leverage of 1
trading_type
No
Supported values: cfd 
margin_type
Yes
Supported value:cross or isolated, defaults to isolated. Only available if leverage_level is not 1.
Parameters	Optional	Description
leverage_level	No	Valid levels: `2`, `4`, `5`, `10`, `25`. Failure to supply these will result in an execution of `spot` order with leverage of `1`
trading_type	No	Supported value: `margin`
margin_type	Yes	Supported value:`cross` or `isolated,` defaults to `isolated`. Only available if leverage_level is not `1`. When `"margin_type": "isolated"` the `funding_currency` is the quote currency and does not support other funding currencies.
funding_currency	Conditional	Supported values are: `SGD`, `JPY`, `USD` when `"margin_type": "cross"`. When placing a BTCJPY order and account does not have JPY but has enough `USD` balance, then specify `"funding_currency": "USD"`. This will automatically switch `margin_type` to `cross`.
order_direction	Yes	Supported values: `one_direction`, `two_direction`, `netout`. Defaults to`two_direction`. When a user has an open Long position in `one_direction`, placing a Short order will be rejected, and vice versa. Use `two_direction` to have an open Long position and an open Short position simultaneously. Decrease the position sizes of a long position, place a short order with `netout`.
take_profit	Yes	Only available if leverage_level is greater than 1. If order side is `buy` the value of `take_profit`must be greater than the order's price. If order side is `sell` the value of `take_profit` must be less than the order's price. This same rule applies to orders that are executed at market. Take profit will be executed as a limit order.
stop_loss	Yes	Only available if leverage_level is greater than 1. If order side is `buy` the value of `take_profit`must be less than the order's price. If order side is `sell` the value of `take_profit` must be greater than the order's price. This same rule applies to orders that are executed at market. Stop Loss will be executed as a market order.
