I appreciated seeing this code, which is very relevant to
an issue I've been trying to solve. I've posted a couple times on this
topic in the past days. It also relates to the topic of loops which
has been discussed recently. Here's the proposed code:
Setup = your buy condition;
Tradedate = ValueWhen(setup,DateNum(),1);
LastTradedate = Ref(Tradedate,-1);
Otpd = Tradedate > Lasttradedate;//only
one trade per day
Buy = Otpd AND Setup;
However, there’s a general
problem with this code, I believe. It probably
works fine most of the time, but is not really doing what you want it
to. The problem is that you are trying to base
a trade on a past result. But that past result is determined by the
current trade.
The idea is
1.
Set up your temporary trade
conditions (setup)
2.
Check to see if those temporary
trade conditions were true in the past
3.
Trade on the basis of both 1
and 2
The problem is that step 1
should really be checking to see if the actual trade (step 3) occurred
in the past. However the current code only
checks whether step 1 occurred in the past. In
some cases this could cause a problem because step 1 may indicate that
a trade has been taken when in fact it has not. I am
not sure I have this right, and if I am right I am not sure
that this can be solved without using loops.
Your thoughts appreciated....

Re: [amibroker] No more than 1 trade per day
Hello Barry,
i also trade forex and have written such code a few months ago.
I have searched my files right now and have found the following code.
Check it out, i have not tested it right now.
Setup = your buy condition;
Tradedate = ValueWhen(setup,DateNum(),1);
LastTradedate = Ref(Tradedate,-1);
Otpd = Tradedate > Lasttradedate;//only
one trade per day
Buy
= Setup;

How can I require that
there be no more than 1 trade per day?
I’m trading forex, on one
currency, and I want to require that if there has been a Buy or Sell
today, then take no more trades today.
Something like: Buy =
conditions AND DayofWeek() > or < DayofWeek() for last Buy or
Sell, but I don’t know how to write it.
The “or <” would allow
for Mondays.
Thanks for your help.
