crossover | Minimal sufficient Envoy xDS for Kubernetes | Service Mesh library

I am trying to plot a circle on the oscillator at the event of a crossover. My goal is to put it where the crossover happened on the oscillator. Using location.bottom/top puts it at the bottom/top while location.absolute doesn't put it anywhere. PLEASE HELP:(

This is the code and a screenshot (Orange circle is where it SHOULD be):

valBottom = crossover(val, valSMA) and val < 0

plotshape(valBottom ? high / 2 : na, style=shape.circle, color=green, location=location.bottom, size=size.small)

I'm having a tough time getting this figured out.

Basically I have an indicator I'm trying to make a condition for bullish vs bearish.

The components are a channel and a moving average, and I want to have the crossover(sma, lower_bound) make the bullish condition true until the moving average crosses above the upper bound and have the bearish condition become true on crossunder(sma, upper_bound)

I have attempted a few different ways but what ends up happening is that the bullish condition only occurs on the crossover bar and doesn't persist until the crossunder.

TLDR I need to make a one time condition (cross) turn a state on and continue until a different cross turns it off.

thanks in advance

(P.S. I had a similar question, but I deleted it and wrote this simplified one)

The script have a starting point from where it start to search for conditions, from this point I need when any of those 3 conditions is met first, to stop plotting anything from that point, inclusive if the same condition is met again in the future.

For the dummy script I used 3 EMA crossovers for each of those 3 conditions, so if close will cross ema50 first, there should be no more cross plots in the future for any of them, basically the script should stop right there.

This is the farthest I could get, my way of doing it is not plotting anything.

Edit: I updated the script according to LucF answer, which work well (no plots or plotshapes plotted after one of those 3 conditions is met, but still I need that first condition/plotshape to be plotted on the chart.

I'm reading PineCoders' FAQ and more precisely how to optimize the code. I want to replace valuewhen in the following scenario. I assume they mentioned it because of the warning about repainting when creating alerts?

Use techniques like this one whenever you can, to avoid using valuewhen().

How should I avoid valuewhen in the following case?

I'm trying to accomplish trade direction (Long/Short/Both) in study mode, just like LucF and PineCoders did here.

• When I select "Longs Only", I expect it to show only long trades, but it doesn't due to the missing the part which finds the range of the candles in the long trade. If you check the link I gave above (Backtesting & Trading Engine [PineCoders]), LucF uses InLong, InShort, InTrade variables. The problem is that his code is older and too overengineered for me and I don't get the idea on how to recreate it.

I said overengineered, because his code includes pyramiding, slippage and other stuff that are now built-in TradingView, probably because back in 2019, PineScript didn't have such features.

The actual idea behind that indicator is to plot alerts and another script which backtests it using that indicator as a source.

• The bar coloring part is not working and it is currently commented, so the code can compile. The problem is the same as above's description. I need to know whether I'm in a long trade direction or short or not in a trade at all. I don't know how to accomplish that part.

I can't figure out why my loop isn't working.

I have a database (36rows x 51columns, its name is "Seleccio") consisting of 3 factors (first 3 columns: Animal (12 animals), Diet (3 diets) and Period (3 periods)) and 48 variables (many clinical parameters) with 36 observations per column. It is a 3x3 crossover design so I want to implement a mixed model to include the Animal random effect and also Period and Diet fixed effects and the interaction between them.

A sample of the data (but with less rows and columns):

I have a green triangle for longs and red triangle for shorts. Barssince is taking from green triangle to another green triangle and from one red to another red. What I want is barssince to be from a green to a red triangle.

So, I'm trying to run a trading bot on medium timeframes (1h - 4h) using the KDJ-indicator. I know it's not the most responsive indicator but it is very reliable, at least on higher time frames (8h - 1D). What I would like to be able to do is use the following script to send BUY/SELL-signals to my bot, BUT ONLY when the asset is not trending down on the 1D-chart. In other words, I would like to run this script:

My idea is to track crude oil commodity prices and trade an ETF based on the movements of Oil.

Logic is:

• If price crosses SMA100 upwards trending for Oil, buy ETF
• If price crosses SMA100 downwards trending for oil, sell ETF

I use a generic SMA strategy but I cannot make it use the data from oil. Based on the plot it uses SMA 100 for the ETF.
