Most Reliable TF for Automated Trading

Hi
i'm new in developing auto trading.
i'm reading a lot of post but can't find anything re the Time Frame they frequently use for automatic trading.

What time frame do you often use on your EA?

Thanks!

A properly designed and written EA will run correctly on any TF on any currency pair. There will be some currency pairs and some TF that produce better results. It becomes more of the choice of the trader as to their preference and that is probably how the defaults should be chosen and where most of the testing should be focused.

But from my experience, I know that whatever assumptions I make, somebody will come up with a combination I never imagined so I limit my assumptions to the minimum and allow for the most flexibility. I remember once writing an EA that I thought could only work on TF of 30M and higher. One guy downloaded it and loved the way it worked on the 5M. When he explained how he was using, it actually made more sense that the higher TF. Of course if you're writing the code for your own personal use, these guidelines can be relaxed. I love designing and writing code and hate fixing it.

hi,

mostly i use higher time frame from 15-240.

small time frame for small TP and SL is bigger than TP, i don't like this actually... with small time frame too much false signal.
example SL=30 and TP=15

with higher TF i can use SL=30-100 and TP=30-200 or more. it depends the ea. i must to know how the ea work...

i like higher TF to put time for the EA have room for trading...

for manual i use 30-one day chart. if use one day i only take a look at 4 h or 1h chart. no bother about the price action moving at small TF and get enough sleep even there is floating loss, if hit SL, let it happened when wrong decision as long as the system has winning ratio bigger than lost.

have a good system and have good profit management.
