how does this instruction work?

[aekzof]

Hello
i already posted a question about this indicator but I found again something that I did not understand

In this indicator Autotrendlinecreated by you or your colleague NinjaTrader_Paul
https://ninjatraderecosystem.com/use...totrendline-2/
Direct link https://ninjatraderecosystem.com/use...425d1651141555

can you explain me how this instruction 128 or 176 works
there is a loop
for (int barsAgo = upTrendEndBarsAgo - 1; barsAgo >= 0; barsAgo--)
{
if (Close[barsAgo] < endBarPrice + (Math.Abs(upTrendEndBarsAgo - barsAgo) * changePerBar))

barsAgo starts when there is a signal
upTrendEndBarsAgo last bar that touches the trend

in barAgo is desincremented
and each time have tested Close[barAgo ]
sometimes barAgo exceeds 30
so how do we test Close[30]? (example)
whereas normally we test the last bar that will close or cross the trend

Thank you for your patient

Hello aekzof,

in barAgo is desincremented
and each time have tested Close[barAgo ]
sometimes barAgo exceeds 30
so how do we test Close[30]? (example)

In the given code the barsAgo is being subtracted on each loop so for it to test Close[30] that would require the upTrendEndBarsAgo to be 30 or greater.

whereas normally we test the last bar that will close or cross the trend

To clarify here, are you asking how to use the indicator as a signal so you could check the last bar value for crossings?
