What is starting day trade buying power (SDTBP)?

Your maintenance excess from the last trading day

Starting Day Trade Buying Power is your account's maintenance excess at the close of the previous day. Unlike maintenance excess, starting day trade buying power is static and will not change throughout the trading day. Your Starting Day Trade Buying Power is essential if you plan on day trading. If you go over your SDTBP when day trading, then it can result in a Day Trade Call (DT).
