I'm working on a TradingView script (Pine) and I would to develop a simply script that draw a rectangle from a start of current day to the end based on my current timeframe from Monday To Friday...
Example: First rectangle drawed from 24/03/2021 to 25/03/2021, Second Rectangle drawed from 25/03/2021 to 26/03/2021, etc...
Any solutions to achieve this result?
Thank's in advance
I think I have understood your request. The below should help assist you
//#version=4
study("Daily Box", overlay=true)
Bottom = input(title="Bottom", type=input.session, defval="0000-2359:1234567")
colourcheck = 1.0
boxheight = input(title="Box Height", type=input.float, defval=3)
DailyHigh = security(syminfo.tickerid, "D", high, lookahead=true)
DailyLow = security(syminfo.tickerid, "D", low, lookahead=true)
dayrange = DailyHigh - DailyLow
BottomLowBox = DailyLow + (dayrange * 0.01 * boxheight)
TopLowBox = DailyHigh - (dayrange * 0.01 * boxheight)
BarInSession(sess) => time(timeframe.period, sess) != 0
//ASIA
BottomL = plot(DailyLow and BarInSession(Bottom) ? DailyLow : na, title="Bottom High", style=plot.style_linebr, linewidth=3, color=na)
TopL = plot(DailyHigh and BarInSession(Bottom) ? DailyHigh : na, title="Bottom Low", style=plot.style_linebr, linewidth=3, color=na)
fill(BottomL, TopL, color=color.purple, title="Fill Box", transp=50)

You folks helped me with another part of this script and I'm making good progress. However, I'm stuck again.
I added a code to produce a dynamic overbought/oversold line on the indicator. That part works great. Now, I'm wanting to add a plotshape when conditions are met to signal long or short. Unfortunately, I can't figure out how to compare a bool variable and a float variable. The dynamic OB/OS lines are floats. The crossover lines are bool.
What I want is for the (green/long) shape to plot when a crossover happens below the dynamic oversold line and the (red/short) shape to plot when the crossunder happens above the dynamic overbought line.
I've tried all kinds of things (var, loop with "while" using sb value as a trigger). I either break the code or I get every crossover plotted. Here is what I have that is stable. I took all my junk that didn't work out:

//OverSold = input.float(-0.1)
calc_smma(src, len) =>
smma = 0.0

smma := na(smma[1]) ? sma_1 : (smma[1] * (len - 1) + src) / len

calc_zlema(src, length) =>

ema2 = ta.ema(ema1, length)
d = ema1 - ema2

src = hlc3
hi = calc_smma(high, lengthMA)

plotshape(shsbCrossOver, "LONG", shape.triangleup, location.bottom, color.new(color.green, 0))
plotshape(shsbCrossUnder, "SHORT", shape.triangledown, location.top, color.new(#cd0808, 0))
//ebc = input(false, title='Enable bar colors')
//barcolor(ebc ? mdc : na)
You cannot compare a bool with a float. It doesn't make any sense and it is not legal in pinescript.
What I want is for the (green/long) shape to plot when a crossover
happens below the dynamic oversold line and the (red/short) shape to
plot when the crossunder happens above the dynamic overbought line.
You want to check if the values you use in that crossover is under your dynamic oversold line at the time of crossover.
OverSoldLine = ta.lowest(sb * 0.5, lengthSignal*100)
shsbCrossOver = ta.crossover(md, sb)
is_good = shsbCrossOver and (md < OverSoldLine) and (sb < OverSoldLine)
In below code, I am getting syntax error for plotshape and several for label. Even for max / min i am getting too many arguments. I used label to get the value from intraburst formula as text. Will need help to resolve these.
//#version=4
study("Intraburst", overlay=true)
truemove = abs(open[2] - close) dayTrueHigh = max(high[1], high,
close[2]) dayTrueLow = min(low[1], low, close[2]) dayTrueRange =
dayTrueHigh - dayTrueLow intraburstLevel = truemove / dayTrueRange *
100
if intraburstLevel > 30
plotshape(series=intraburstLevel, text="ON", style=shape.circle, location=location.abovebar, color=color.green, size=size.normal) else
plotshape(series=intraburstLevel, text="OFF", style=shape.circle, location=location.abovebar, color=color.red, size=size.normal)
label = label.new(bar_index=0, yloc=y_top, xloc=xloc.bar_index,
text=tostring(intraburstLevel, "0.00"), size=size.large,
color=color.black) label.location = location.top label.y = y_top
label.x = x_right label.text = tostring(intraburstLevel, "0.00")
In series, use a ternary
Something like that:
plotshape(
intraburstLevel > 30 ? intraburstLevel : na,
text = "ON",
style = shape.circle,
location = location.abovebar,
color = color.green,
size = size.normal)
plotshape(
intraburstLevel <= 30 ? intraburstLevel : na,
text = "OFF",
style = shape.circle,
location = location.abovebar,
color = color.red,
size = size.normal)
and the label
label.new(
bar_index,
close,
tostring (intraburstLevel, "##.00"),
color = color.black,
textcolor = color.white)
I've got a simple historical camarilla indicator that I'm mostly happy with, save for one detail. My horizontal lines are plotted from 9:30 until 9:30 the next day, except on the Friday to Monday transition. I don't really understand why this happens. So what I'd like is for the lines to start from 7:00 to 18:00 every day, in order to align with price action in the pre/post market. I'm not very good at pinescript, and I can't seem to find a solution. Is this even possible using 'plot', or should I be using 'line.new'? Any help would be greatly appreciated. The script I have is as follows;
//#version=5
indicator('Camarilla Levels', overlay=true)
// User inputs
showHistoricalCams = input(title='Show Historical Cam Pivots', defval=true)
//Camarilla Calculations
tR3 = close + (high - low) * 1.1 / 4.0
tS3 = close - (high - low) * 1.1 / 4.0
tR4 = close + (high - low) * 1.1 / 2.0
tS4 = close - (high - low) * 1.1 / 2.0
//Pivot Range
_tR4 = request.security(syminfo.tickerid, 'D', tR4)
_tR3 = request.security(syminfo.tickerid, 'D', tR3)
_tS3 = request.security(syminfo.tickerid, 'D', tS3)
_tS4 = request.security(syminfo.tickerid, 'D', tS4)
//Plot Historical Cam
plot(showHistoricalCam ? _tR3 : na, title=' R3', color=_tR3 != _tR3[1] ?
#eeeeee00 : #ff000080, style=plot.style_line, linewidth=1)
plot(showHistoricalCam ? _tR4 : na, title=' R4', color=_tR4 != _tR4[1] ?
#eeeeee00 : #ff000080, style=plot.style_line, linewidth=1)
plot(showHistoricalCam ? _tS3 : na, title=' S3', color=_tS3 != _tS3[1] ?
#eeeeee00 : #008000FF, style=plot.style_line, linewidth=1)
plot(showHistoricalCam ? _tS4 : na, title=' S4', color=_tS4 != _tS4[1] ?

I've tried setting time parameters, but can't make the script work.
We know that RSI plotting range is between 0 to 100.
Is it possible to change a plotted indicator line so that it will fluctuate in an extended range, say -50 to 100 ?
In simple way I want it to be (stretched) so I can easily draw trend line on the RSI line.
Attached photo is sample of what I mean on is perfect , one that I have is not like it.
I want the the RSI to cross the green and red area without affecting the movement of the indicator. I just want it to be stretching.

You can use normalize() function:
//#version=5
indicator("My script")
normalize(_src, _min, _max) =>
// Normalizes series with unknown min/max using historical min/max.
// _src : series to rescale.
// _min, _min: min/max values of rescaled series.
var _historicMin = 10e10
var _historicMax = -10e10
_historicMin := math.min(nz(_src, _historicMin), _historicMin)
_historicMax := math.max(nz(_src, _historicMax), _historicMax)
_min + (_max - _min) * (_src - _historicMin) / math.max(_historicMax - _historicMin, 10e-10)
rsi = ta.rsi(close, 20)
rsiNormalized = normalize(rsi, -50, 100)
plot(rsiNormalized)
hline(-50)
hline(100)
EDIT
In your case, since we know the scale will always be between 0 to 100, we can use math to solve the issue much more accurately:
//#version=5
indicator("My script")
rsi = ta.rsi(close, 20) // this will give a value between 0 to 100
// find the value compared to a scale of 100
rsiPerc = rsi / 100
// multiply by the new range to get the position of rsi on the new range
rsiOnNewScale = rsiPerc * 150
// place the newRsi on a scale of -50 to 100
newRsi = rsiOnNewScale - 50
plot(newRsi)
hline(-50)
hline(100)
Or in short:
//#version=5
indicator("My script")
rsi = ta.rsi(close, 20) // this will give a value between 0 to 100
newRsi = (rsi / 100 * 150) - 50
plot(newRsi)
hline(-50)
hline(100)
in the following strategy all time (trades) open and close in the same time, so I pay only fees.
I have written to tradingview assistance, they have said me (and send) to put OPEN LONG and CLOSE LONG (the first 2 lines in strategy).
But I still have the same problem, I don't know why.
All test are ok, I think that problem is with TRAIDINGVIEW HUB, but I am not scure.
Thanks for your attention and time
