Script Trigger as Soon as MACD Diff Crosses to Negative

[Tomahawk6117]

Hi everyone,

The script below triggers when the stock price goes below the market open (9:30 a.m.) price for the current day and when the MACD Diff is negative. The script below triggers after the candle closes. Is there a way to adjust the script so that the script triggers as soon as the MACD Diff crosses below zero instead of waiting until after the candle closes? Thank you very much for your time and your help.

input sell_percent_gain = 0.0;
input price1 = close;
input start = 0930;
def daystart = secondstillTime(start) == 0;
def dayopen = if daystart then open else dayopen[1];
def daydiff = round(price1 - dayopen,2);
def pergain = round(100*daydiff/dayopen,1);
def d = MACDHistogram().diff;

input trigger_on_all_prices_below_stop = yes;
def sell1 = if (daystart or trigger_on_all_prices_below_stop) and pergain <= sell_percent_gain and d < 0 then 1 else if d < 0 and pergain crosses below sell_percent_gain then 1 else 0;

plot z1 = sell1;

the problem with the logic you have is that it shows after the close because you dont know if the bar will close green or red. it can BRIEFLY be red only to end up closing green. if you have it as soon as it crosses but yet it ends up closing green, you are going to end up with many "unwanted alerts".

Thank you very much for your response @XeoNoX. So there is no way to formulate the script so that it triggers if the MACD Diff crosses below zero before the candle closes? I am not interested in how the candle closes, I am interested in when the MACD Diff crosses below zero, even if it does not stay there until the candle closes. Thank you again for all of your time and your help.

try changing

d < 0

to

d crosses 0

Thank you @XeoNoX, I will give this a try, thank you very much for your help.

@Tomahawk6117 Just remember that until a bar closes, close == last so if you are parsing the current candle you will end up with false positives... This is why @XeoNoX hinted to wait for candle close which will yield an instantaneous yet more accurate result... If we don't wait for close then the price may drop below zero at the open of the candle, or anytime before close, and then switch directions and that will case a false positive and potential reversal/loss...

Thank you very much @rad14733, I really appreciate it. I am primarily using the script for the purpose of a conditional order where I would like the script to trigger as soon as the MACD Diff crosses below zero even if it does not result in being below zero at the end of the candle. I completely understand what you are saying though, and I really appreciate all of your time and your insights.
