Maker commission on bStocks - 0%. I calculated what that means.

All markets are closed on weekends, so I wasn’t counting the price, but the cost of my actions.

My orders, $SPCXB /USDT at 02:19:
taker 0.1%
maker 0%
BNB discount is not active - no available BNB

Order book at 02:20:
bid / ask: 139.69 / 139.70
spread: 0.01 USDT = 0.0072%

Two full-turn routes: I bought and then sold.

Using market orders, taker twice:
0.1% + 0.1% = 0.2% commission
plus the spread, because I buy at 139.70 and sell at 139.69 = another 0.0072%
total 0.207%

Using limit orders that are already sitting in the book, maker twice:
0% + 0% = 0
and the spread here isn’t against me—it's in my favor

In the price it looks like this:
139.70 x 0.207% = 0.29 USDT
daily range of the pair 140.55 - 139.30 = 1.25 USDT
0.29 / 1.25 = 23%

To make the taker case just break even and get your money back, you need almost a quarter of the pair’s entire daily move.

What I understood.

For two weeks I calculated the entry threshold: 5 dollars, fractional parts, 66 owners of one share. But the entry threshold and the cost of using it are different numbers. The first one here is almost zero. The second one depends not on the amount, but on whether I can wait.

Limitations: a limit order may not execute at all, meaning at 0% I sometimes pay with time and the risk of not getting filled. Spread is one slice, at night on weekends. With BNB, taker would be 0.075%.

A cheap entry and cheap trading are not the same thing.
