Ema Crossover with 3 orders

I made a strategy in tradingview for the ema 5 - ema 12 cross as follows :

strategy("traderxo 8m")

ema12 = ema(close, 5)

ema21 = ema(close, 12)

long = ema12 > ema21

short = ema21 > ema12

strategy.entry("Long", strategy.long, 50000.0, when = long)

strategy.entry("Short", strategy.short, 50000.0, when = short)

strategy.close("Long", when = short)

strategy.close("Short", when = long)

=  =  =  =

condition for long:

Ema 5 crosses above Ema 12, based on candle close. Will have three trade entries:

entry 1 : market price 0.3 lot

entry 2 : price -5 pips 0.3 lot

entry 3 : price -15 pips 0.3 lot

close all three long positions when bearish ema cross between ema 5 and ema 12

=  =  =  =

condition for short:

Ema 5 crosses below Ema 12, based on candle close. Will have three trade entries:

entry 1: market price 0.3 lot

entry 2: +5 pips 0.3 lot

entry 3: +15 pips 0.3 lot

close all three short positions when bullish ema cross between ema 5 and ema 12
