Hi, how does one write a formula and which also gives visual buy and sell arrows, and also runs for a back test...... buy when 13 period EMA crosses 21EMA on close (completed candle) of a 1 minute chart with a condition that the 21 minute EMA of a 5 minute chart should be above 13 EMA in 5 mins chart.
Thanks in anticipation Cheers Ravi
