the shorter time span the more opportunity?

I thought is was

but now I changed my idea

for a specific strategy ,it seems there is an optimistic time span

longer or shorter it will not be so efficient

in detail, becoz I trade hsi,I find 50tick works well for me

if I change to 30 tick ,It will work but not efficient as 50 tick

I don't know why

 

here r 2 pics

the same strategy but one is 30 tick chart the other 50 tick chart

 

50 tick chart

 

Have you fully backtested your strategy? Some unprofitable strategies suddenly became profitable this year, but they are not expected to be long-lasting. How long test period did you get these 400/700 points optimized profit ? One month ? one week ,or so far this year ?

 

both r last month



I usually backtest for a month

then apply the parameter to the next month

 

Yes the shorter your time frame, the most "waves" you can catch, and as such its more profitable, until...

A. Commissions become to high for the small movement expected.

B. Your time frame is too short that orders don't get enough time to be filled.

C. Time is too short that it doesn't appears to follow technical analysis anymore, as some scalpers have found the hard way.
