BitMEX semi auto trade tool

[I would like to pay for the performance fee without making a request for the start fee.] I want you to create a program that automatically trades on BitMEX virtual currency exchange transactions under certain conditions using the API. The usage environment is assumed to be Web(+mobile) I/F. ----------------------------- I want to execute an order automatically using API of virtual currency exchange called BitMEX. The condition to be specified is that if the number of waiting orders is less than X, the purchase order is made at a price lower than the current market price by Y dollars (And I want to shift the price like this, Y-50[=Y-50x1], Y-100[=Y-50x2], Y-150[=Y-50x3] ...), There is one. And the other is to place an order to sell at $ Z (And I want to shift the price like this, Z+5[=Z+5x1], Z+10[=Z+5x2], Z+15[=Z+5x3]...) higher than the market price if there is an open position. Each instruction is cyclically monitored every A seconds to monitor the status. I want to make these algebras variable by inputting numerical values from the interface. And it would be best for me if I could implement a mechanism to restrict usage by user id and password. Best regards
