Static support and resistance levels calculated from the previous period’s high, low, and close. The “pivot” (central level) is the average of high+low+close; additional levels (R1, S1, etc.) are derived from that. Day-trading EAs use pivot levels as targets or bounce points. While MT4 doesn’t have a built-in pivot function, these can be coded using historical price data; cTrader/NinjaTrader often offer pivot indicator scripts or functions.
