error on place trade order type TRAILING_STOP_MARKET‏

[aref-r]

hello,
I want to place trade order type TRAILING_STOP_MARKET.
please check if I set correctly these 3 values ?

for example when coin current price is 3 usdt.

(leverage => 4)
(
'price' => 0.2 (distance of trail by usdt),
'quantity' => 5 / 3 * 4 (my margin is 5 usdt divide by coin current price multiply by leverage) ,
'type' => 'TRAILING_STOP_MARKET',
'activationPrice' => 3.2 (when the price arrive to 3.2 usdt the trail start with 'price = 0.2 usdt' distance),
)

this means stoploss price move (trail) from 2.8 to 3 when price come to 3.2 usdt.

is it incorrect ?

because I get this error :

[code] => 110425
[msg] => Please ensure that the minimum nominal value of the order placed must be greater than 2u

and when I set the price field equal the current price of coin, I get this error :

[code] => 110418
[msg] => Must be less than the maximum trailing distance of 1.3158

should I open TRAILING_STOP_MARKET with minimum margin of 250 usdt ?
