The exact time estimation of when a member's coin buy/sell order transaction can be successful cannot be known with certainty. Member order transactions will be executed influenced by the main thing, namely the order transaction method used.

If you use the market / instant order method when buying / selling coins, then your order transaction will automatically succeed following the best price available in the Indodax market order book at that time. But if you use the limit order method, the transaction will be executed if there is a buy/sell in accordance with the price you specify and the volume is fulfilled. It is expected that you have careful calculations in determining the transaction method to be used, because each transaction method has a different fee.
