I want to trade $4k in equities each day (sell all next day and then buy $4k more), but am not sure of the math needed for account balance to avoid a margin call or any other violation. It will be a combination of Long and Short positions.

I have read:

> **[Margin and Short Selling](https://docs.alpaca.markets/docs/margin-and-short-selling#margin-calls)**
>
> In order to trade on margin or sell short, you must have $2,000 or more account equity. Accounts with less than $2,000 will not have access to these features and will be restricted to 1x buying power.This is only for Equities Trading. Margin Trading...

and looks like I don’t need to wait for funds to settle with a margin account.

So if we say I incur $100 maximum account equity loss daily and let’s say I replenish the account every 5 business days and let’s say those funds transfer immediately for the sake of argument.

So $4500 would be enough to not get margin called and would I also avoid all possible violations? Also what is the max margin multiplier x1 do on the account dashboard?

Scenario 2- Buy $10,000 of a security with a 100% requirement  
DTBP is $100,000 and RegT buying power is $25,000. When the order is placed, DTBP will be reduced by 4 x 10000 ($40,000) to $60,000. RegT buying power will be reduced by 2 x 10000 ($20,000) to $5,000.

Or would I need $18k of my own money to buy $4k worth of stock?
