Need help changing this script to long only

Not sure how to fix this but i want to take all the short trades out as i believe this wil reduce the drawdown.

Any help would be greatly appreciated


//version=2
strategy("MOMENTUM", overlay=true)

//RSI Section
length = input(2, "RSI Period")
overSold = input(30, "Oversold Level")
overBought = input(70, "Overbought Level")
price = close
vrsi = rsi (price, length)

//VSTOP Section
vlength = input(5)
mult = input(2)
atr_ = atr(5)
max1 = max(nz(max_[1]), close)
min1 = min(nz(min_[1]), close)
is_uptrend_prev = nz(is_uptrend[1], true)
stop = is_uptrend_prev ? max1 - mult * atr_ : min1 + mult * atr_
vstop_prev = nz(vstop[1])
vstop1 = is_uptrend_prev ? max(vstop_prev, stop) : min(vstop_prev, stop)
is_uptrend = close - vstop1 >= 0
is_trend_changed = is_uptrend != is_uptrend_prev
max_ = is_trend_changed ? close : max1
min_ = is_trend_changed ? close : min1
vstop = is_trend_changed ? is_uptrend ? max_ - mult * atr_ : min_ + mult * atr_ : vstop1
plot(vstop, color = is_uptrend ? green : red, style=circles, linewidth=2)

if vrsi > overBought
strategy.entry("Buy", strategy.long, comment="Buy")

if vrsi < overSold and vstop > price
strategy.entry("Sell", strategy.short, comment="Sell")
