Comparing BB with RSI is impossible, since the first one refers to prices, while the latter to a range (0-100).
But for other indicators, yes it is easy, let’s say you want to know whether there’s been a CROSSOVER in anyone of the last 3 bars:
|
FastMA = average[5,0](close) SlowMA = average[25,0](close) x = summation[3](FastMA CROSSES OVER SlowMA) //x will be true if the crossing occurred within anyone of the last 3 bars IF x THEN...... |
If you want to test specifically the 2nd previous bar you can write:
|
x = FastMA[2] CROSSES OVER SlowMA[2] //x will be true if in the 2nd previous bar there's been a crossover |
or (it works the same):
|
x = FastMA CROSSES OVER SlowMA //x will be true if there's a crossover IF x[2] THEN //you test x for the 2nd previous bar . . ENDIF |
