It seems to open the positions correctly now! But i’m still missing on how to put the stop loss on the high/low of the entry candle. Also in your example @js the postion should be closed at 15:55 after crossing under the low of the entry candle. Any suggestion? Current code version below:

// Entry Conditions
once highentry=0
once lowentry=0

if time= 153000 then
highentry=high
lowentry=low
endif

cl=close crosses over highentry
cs=close crosses under lowentry

// Time Conditions
t=time>=153500 and time< 154000

// Enter Long
if not onmarket and cl and t then
buy n contract at market
endif

// Enter Short
if not onmarket and cs and t then
sellshort n contract at market
endif

Ok i think i managed to solve the issue changing with:

// Stop Loss Conditions
sll=abs(close[2]-low)
sls=abs(close[2]-high)

But looking at the backtests, putting the stop loss on the high/low of the opening range candle (so at the daily high/low) instead of the candle where the position was opened (as i wanted to during last posts) seems more effective for gains. Below the first version of the system (i’m still figuring out if it’s necessary to implement the VWAP condition) on NASDAQ 5M – 1.5 Contracts (939€ atm)

// Parabolic Long/Short v1 by Francesco
// ProRealCode.com - 20230316
// NASDAQ - 5M

// Setup
defparam cumulateorders=false

n=1.5

once long=1
once short=1

timeframe (1 day)
// Filter
x=3

if (close-close[1])/close*100>=x then
increase=1
decrease=0
elsif (close-close[1])/close*100<=-x then
increase=0
decrease=1
endif

timeframe (default)
// Entry Conditions
if time=153000 then
highentry=high
lowentry=low
endif

cl=close crosses over highentry
cs=close crosses under lowentry

// Time Conditions
t=time>=153500 and time<154000

// Stop Loss Conditions
sll=abs(close-low)
sls=abs(close-high)

// Enter Long
if long then
if not onmarket and decrease=1 and cl and t then
buy n contract at market
set stop loss sll
endif
endif

// Enter Short
if short then
if not onmarket and increase=1 and cs and t then
sellshort n contract at market
set stop loss sls
endif
endif

// Trailing Stop
trailingstart=200
trailingstep=5

If not onmarket then
newsl=0
endif

if longonmarket then
if newsl=0 and close-tradeprice(1)>=trailingstart*pipsize then
newsl=tradeprice(1)+trailingstep*pipsize
endif
if newsl>0 and close-newsl>=trailingstep*pipsize then
newsl=newSL+trailingstep*pipsize
endif
endif

if shortonmarket then
if newsl=0 and tradeprice(1)-close>=trailingstart*pipsize then
newsl=tradeprice(1)-trailingstep*pipsize
endif
if newsl>0 and newSL-close>=trailingstep*pipsize then
newsl=newsl-trailingstep*pipsize
endif
endif

if newsl>0 then
sell at newsl stop
exitshort at newsl stop
endif

Few details about the system:

• Entirely based on price action
• Pretty easy to optimize (just 1 value to edit)
• No optimization needed for stop loss, just play with the trailing stop
• Running just the Long version drastically decreases drawdown but generates less gains
