问题 Try to plot the value of the highest bars between current bar and the last cross of ema(50) and ema(200) using barssince(cross(ema50,ema200)) . The function highest() wants an integer and the Barssince gives a series integer . All variants getting the error that pine connot compile with error: line 4: Cannot call `highest` with arguments (series[integer]); available overloads: highest(series, integer) => series; highest(integer) => series Script. //@version=3 study("My Script") o = 0 o :=

问题 If I want to compare the close of today with the high of the last 4 days, what is the format? I have used _hi = close > high[4] ? 1 : 0 But that only counts the high 4 days ago, not the days in between. I have tried _hi = close > high[1,2,3,4] ? 1 : 0 Error message 回答1: You can use highest() for that purpose. highest(source, length) → series You need to be careful though. close > highest(close, 4) can never be true . Because, if the current bar's close price is the highest among those 4 bars,

问题 I started with a question on how to programmatically draw a time/range based box/rectangle to frame a trading session, but came to the realization that Pine is not capable of doing so... However, I understand Pine v4 introduces the ability to draw line objects and wonder if anyone can point me in the right direction for code to draw session lines instead. By that I mean hi & Lo for the start/end time specified (i.e. highest & lowest value for the time period) would be much appreciated? I am

问题 In light of this post I'd like to ask why the script hereunder works for [a,b] but doesn't work for [c,d] . Cannot find any documentation that explains why this doesn't work. This example is only for 2 return values, but in reality I'm going to create a function with 6 or more variables to be returned in one go. I'm trying to avoid having to enter 6 different lines, because I'll be entering this data every trading day (the function will be date-depentent and I already have code for that). So

问题 As mentioned in the answer to Timezone convertion between tickers by Dennis T, we can use the security() function to get the time in another timezone. Now I was trying to get times from 2 different timezones. Ticker CL1! trades on Nymex in New York, in timezone UTC-4 . Ticker ES1! trades on CME in Chicago, in timezone UTC-5 . We can see that from the symbol info In order to visualize that time difference, I've created a small script that plots the time in both timezones. //@version=4 study(

问题 This is my example script //@version=4 study("", overlay=true) // Colors C_FORECAST_HIGH = color.red C_FORECAST_LOW = color.red C_FORECAST_CLOSE = color.blue C_ERROR_HIGH = color.yellow C_ERROR_LOW = color.yellow C_ERROR_CLOSE = color.lime // Plot styles P_STYLE_FORECAST = plot.style_line // } // ————— Hide the connection line when we plot horizontal levels // When plotting with plot.style_line or plot.style_linebr, lines are normally connected. // We are plotting the levels as horizontal

问题 enter image description hereIm trying to make a strategy that buys at the 55 day high and sells at the 20 day low. The probles is that i want to add a stoploss. The stoploss needs to be at 5 procent from the entry. This is what i already tried. //@version=4 strategy("Turtle Project",overlay= true) entry_long_2 = input(55, title="entry_long_2_input" ,minval=2) profit_long_2 = input(20, title="profit_long_2_input",minval=1) cond_L_2 = float(na) cond_L_2:= if high[entry_long_2] >= highest(high

问题 This is a follow-up to my previous question Plotting custom data - daily = ok, weekly = not ok. The comments on the accepted answer suggests that the state of a var inside a function is persisted throughout successive calls to that function. This proved to be correct, because removing the var solved my problem. However, I now have a test case that seems to prove the opposite. In the script below, variable b seems NOT to be persisted. Function f2() has to be called on every bar in order to
