Say from a specific timeline - for eg: Mar 2020 - count the number of instances when RSI crossed WMA. ( only on Weekly charts).
Count is incremented only when RSI comes below WMA and then crosses from below.
So far written the code as below. It highlights as a band the place where RSI crosses WMA.
What I would really like if I can use a counter. Also to do this ONLY on weekly charts.
//#version=5
// RSI WMA EMA
indicator(title="RSI EMA Crossover", overlay=false)
src = input.source(close,title="Source")
len = input.int(9, minval=1, title="RSI")
up = ta.rma(math.max(ta.change(src), 0), len)
down = ta.rma(-math.min(ta.change(src), 0), len)
rsi = down == 0 ? 100 : up == 0 ? 0 : 100 - (100 / (1 + up / down))
wmaLength = input.int(21, title="WMA")
emaLength = input.int(3, title="EMA")
wma = ta.wma(rsi, wmaLength)
ema = ta.ema(rsi, emaLength)
longcond = ta.crossover(rsi,wma)
plot(rsi, color=color.red, linewidth=2, title="RSI")
plot(wma, color=color.blue, linewidth=2, title="WMA")
plot(ema, color=color.green, linewidth=2, title="EMA")
bgcolor(longcond ? color.silver: na)

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)
I want a strategy to Take Profit/Stop Loss to be based on the ATR (plus multiplier). However, I want it to be whatever the readings were at the point of entry, not simply the last candle (which is what it seems to be doing). Weird thing is that I have other strategies that use this approach, and they seem fine, so I'm really stumped by what I'm doing wrong.
Any help would be much appreciated!

You can use the hline and fill functions

i'm trying to find a way to make a indicator like rsi or stochastic but be able to adjust the output by a percentage. For example RSI signal that is increased by a percentage of what i would output by default. So it normally show 70 but is increased to 80 e.g.
Is there a way to do this? I've been scrolling through the manual for hours but couldnt find it.
Any help is appreciated

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
