How do you confirm a trend with macd

HI,
If you want to confirm a trend it doesn’t make difference between downtrend or uptrend how to you determine it with macd?
For example ,I think for confirmation of a downtrend if the macd shoes -0.90 it’s a downtred .What do you think?
Thanks

MACD is interpreted in three forms: convergence, divergence and cross over. Either you are trading on short, medium or long term. The cross over is the confirmation of trend while the convergence and divergence is like retracement like that of fibonnacci. But be aware that confirming the trend on MACD with the simple moving average might be necessary.
