Incrementing indicators

[ezrollin]

If an indicator is sending 1 or 0 or -1 to my strategy builder, how can I catch it on only the first time it hits 1 or hits -1?
(Without going into the indicator and using Variable++; and incrementing it?) thanks

Hello ezrollin,

Thanks for your post.

If the indicator is providing a signal plot, that means the plot's previous values can be accessed. The plot will have a value on each bar and will be +1, -1, or 0. Typically it would output a zero when there is no signal and then the +1/-1 when there is a signal.

So if you check for the previous bar value of the plot is 0 and the plot's current bar value is 1 then you have detected that the indicator has just changed. Likewise, you can check if the previous bar value of the plot was 0 and the current bar value of the plot is -1.
