MT4 indi alert for high low

Hi fellow FF members,

I want to ask if you know of any MT4 indicators out for the conditions:

a. when candle closes with a high and low, with options for choosing the TF, for example H4 or daily

b. then if current price reaches this high or low (or close to it) of that candle having the option of 1, 2 or 3 previous candles back

Then MT4 will do two things:

1. sound an alert
2. send an email

Thanks for the attention
