MultiCharts: Trading Software for Automated Trading and Backtesting

I thought i had the position sizing figures out om binance for trading spot pairs like btc.usdt and eth.usdt etc
but no,

I am currently using a formula as per below, but this does not achieve the expectation to end up with the position size amount for the trade, at binance as set as
POSITIONAMT variable.

NC=ROUND(POSITIONAMT/(Bigpointvalue*C),0);

Anyone can point me in the right direction ?

I am only trading spot and not futures, so all spot pairs should work to have the same formula for position size.


Thanks

Here is the formula to calculate a position size for Binance:
Position cost / close / BigPointValue.
