Stop loss order seems to not work when the delta is small

**Describe the bug**
When the stop loss order is created with small delta from the market price, I am getting the error: "stop price must be less than base_price - 0.01", even though I am taking care to send < base_price-0.01 value. See the code and response below:

code:
ticker = 'OCGN'
quantity = 1
symbol_price = api.get_last_trade(ticker).price
print(symbol_price)
k = min(round(symbol_price - 0.04,2), round(symbol_price * 0.998, 2))
print(round(symbol_price - 0.04,2))
print(round(symbol_price * 0.998, 2))
print(k)
api.submit_order(
symbol=ticker,
qty=quantity,
side='buy',
type='market',
time_in_force='day',
order_class='oto',
stop_loss={'stop_price': k} # stop loss
)
