Control flow

if / else if / else

if (rsi[0] < 30) {
    OrderSend(nifty, BUY, 1, 0, 0, 0, INTRADAY, DAY, "oversold");
} else if (rsi[0] > 70) {
    OrderSend(nifty, SELL, 1, 0, 0, 0, INTRADAY, DAY, "overbought");
} else {
    // do nothing
}

while, for, foreach

int i;

// while — increment with i = i + 1 (++ is only valid in a for header)
i = 0;
while (i < 3) {
    i = i + 1;
}

// for — the header may use i++, i += 2, etc.
for (i = 0; i < 5; i++) {
    if (i == 2) continue;   // skip this iteration
    if (i == 4) break;      // stop the loop
}

// foreach — iterate any list or array
int[] strikes = [24000, 24500, 25000];
foreach strike in strikes {
    // use strike
}
foreach ord in OpenOrders() {   // e.g. walk your open positions (see "Positions & orders")
    // ord.Symbol, ord.Volume, ord.Profit ...
}

The compound operators (++, --, +=, -=, *=, /=) are only valid inside a for header. Elsewhere, use x = x + 1;.
