show me how to make MACD (Main x Zero)

[Luqmaan]

Can someone please show me how to set MACD up so that it can buy/sell when the MACD main crosses the zero line.

I know how to make macd main cross macd signal
I also know how to shift the candles. Please understand my question has nothing to do with any of that.

When I try and make

MACD main
×>
VALUE/NUMERIC/ 0

The indicator gets a seizure and buys and opens positions continiously until im bankrupt.

Even tried changing to 0.0000
To no avail.

Please help
