Create a Pine Script backtest for BTC/USD that will buy Bitcoin when price moves above the 50 EMA and sell when it goes below the 50 EMA. Set the stop loss at 2 times the average true range of the entry candle.
strategy("50 EMA BTC/USD", overlay=true)
longCondition = crossover(close, ema(close, 50))
shortCondition = crossunder(close, ema(close, 50))//Buy when price crosses above 50 EMA
if longCondition
longEntryPrice = close
strategy.entry("Long", strategy.long)//Sell when price crosses below 50 EMA
if shortCondition
strategy.entry("Short", strategy.short)//Set stop loss at 2x ATR of entry candle
stopLoss = entryPrice - (atr(14) * 2)
strategy.close("Long", stop=stopLoss)
strategy.close("Short", stop=stopLoss) -
@ChatGPT请用中文润色改写这段话:
input手动选择特征生成事实数据库,根据这些特征推导出其他动物特征,最终推导出动物种类
判断输入的事实库是否包含规则1-8的集合,如果包含则向事实数据库中加入相应规则对应的事实。
如:选择特征中包含特征2则可根据rule1: if 动物有毛发2 then 动物是哺乳动物21,向事实数据库中加入特征21
判断输入的事实数据库是否包含规则9-15的集合,如果包含则输出相应规则所对应的动物
如:经过上述规则1-8推导后的事实数据库为【4,5,21,22】,rule15 = [22, 4, 5]为其子集,则可判定动物为信天翁31
