Pine Script v5 Strategy not giving entries

Question

I've tried to create a Pine Script strategy and I've reached the point where there are no errors prompted by the IDE but the strategy didn't give any entries. I've tried to understand how to fix the issue, I've searched for other similar questions, I've checked if I was missing something with the Pine Script User Manual and at some point I've even tried asking ChatGPT how to fix that but couldn't have any better results. I would really appreciate any help as I'm learning everyday how to deal with the Pine Script language and couldn't improve if it was not for all the usefull contents gathered on platform like this one.

Answer 1

the script has many errors. fix it step by step

1. replace longPosition and shortPosition with strategy.position_size
2. remove SL and TP (temporarily). first fix long and short

something like this

if buysignal and strategy.position_size <= 0
    strategy.entry("Long", strategy.long)

if sellsignal and strategy.position_size >= 0
    strategy.entry("Short", strategy.short)

at this point, there are only short entries
fix long

3. for debug, plot vstop1

plot (vstop1)

now you can see why there is no long trigger

it seems that this rule is wrong

buysignal = is_trend_changed and close - vstop1 > 0
