If statements and bool variable

[NinjaTrader_PatrickH]

Hello Brian,

Pi is correct. You can call the bools in such a manner, for example equals false can be !B2_SU.

I am new to C# and am learning by working my way through strategies found in the Ninjascripts library. I'm having trouble understanding the logic in one particular section of the PZO Strategy.

//UpTrendRules
			if (Close[0] > EMA(EMAPeriod)[0] &&	ADX(ADXPeriod)[0] > 18)
			{
				if (CrossAbove(PriceZoneOscillator(PZOPeriod), -40, 1))
					EnterLong("Buy1");
				
				if (CrossAbove(PriceZoneOscillator(PZOPeriod), 0, 1))
					B2_SU = true;
				
				if (B2_SU && CrossAbove(PriceZoneOscillator(PZOPeriod), 15, 1))
				{
					EnterLong("Buy2");
				}				
			}

The "B2_SU" variable is a bool variable that is by default false. As you can see above if it crosses above 0 in the last bar it is true. My issue is I don't understand the next line. "If B2_SU... and PZO crosses above 15 then enter long." If B2_SU what? There's no action there. I could understand if it said if B2_SU equals true and ...

Is there an inherent code in an if statement with bool variables that I haven't learned yet? Please translate if you could be so kind.

Thanks!
Brian

You are correct. It is a short way of saying if (B2_SU == true && ....)
You will gradually find this natural later on, especially if the variable name is self explaining. For example:

if (RSI_Overbought && ... ) EnterShort();

Cheers.
