Binance Futures Settings

[ibenxs]

Hello friend, I want to ask for input because this service does not provide trading paper. I was worried before the loss occurred so I asked. I have no futures trading experience before.

A. First problem (NO LEVERAGE):
I trade Binance FUTURES, each pair has a different ticksize, for example (USDT = USD):

XRPUSDT = 1.3851
BNBUSDT = 598,727
DOGEUSDT = 0.306200
minimum purchase = USD 5

I'm not sure about my ticksize setting for the price. the method that I have used so far is:

XRPUSDT = 1.385, ticksize = (0.0001)
BNBUSDT = 598,727, ticksize = (0.001)
DOGEUSDT = 0.306200, ticksize = (0.000001)

Min.shares     = 0.1 //(1 or 0.1 I still don't know)
Min.PosValue   = 5;
RoundLotSize   = 1;
Deposit Margin = 0; //(because NO Leverage)
PointValue     = 1;

is the method above correct?

B. Second problem (LEVERAGE 2x):
Because the futures market has a choice of 1x to 125x leverage.How if the case is using the leverage i 2x, my method is:

XRPUSDT = 1.385, ticksize = (0.0001)
BNBUSDT = 598,727, ticksize = (0.001)
DOGEUSDT = 0.306200, ticksize = (0.000001)

Min.shares     = 0.1;// (1 or 0.1 I still don't know)
Min.PosValue   = 5;
RoundLotSize   = 1;
Deposit Margin = -2; //(LEVERAGE 2x or 1:50)?
PointValue     = 1; //( 1 or 2)?

is the method above correct?

thanks for your attention
