my little advice for those interested in positional trading (especially contra positional trading):
First of all, if one decides to go short (or buy put) when the market in an uptrend, for example, then one should not take such position only because of emotional reasons that market had gone up a lot, it's over-bought, etc. Yes, these are also important, but they are secondary - they will not give you an idea of entry point.
ONLY CHART-READING & STUDYING will provide you with a level to enter a positional trade (contra or otherwise); and also with a reasonable SL.
These important levels are known as RSR (resistance-support-resistance) levels. On charts, they show that they do not break easily without meaningful reaction - sort of "lakshman rekha". In other words, they act as very strong support while coming down and as resistance, while coming up.
Usually, these are round figure nos. with +/- 15pts. - but not in every case, as chart will tell you.
And positional trading does not mean that you should have a 100 pt SL from your entry level - let only the chart say..
I'll give two recent instances:
When Nifty SPot was near 3800, I had bought a call option - not because it had fallen much, oversold, etc.. no, these are secondary - charts told me that 3775 is a very good RSR level. (I had also posted about this level). So, I had kept my SL below 3775 (in options, one can keep a bit comfy round figure of 3750)
Yesterday, I had mentioned about 4515-4535 band resistance. This was another good RSR level, as per the charts, which I used along with some indicators like over-bought, downward sloping line (from Jan peak), profit-booking time, etc.... I had bought Put option, with SL above 4550 (comfy, as per charts - 4570)....
Contra trend trade is very risky, but not unreasonable - if you combine it with good/reasonable entry levels (and not just emotions), then it can be rewarding...
For finding a good RSR level, one should have intraday charts beginning from previous month (sometimes last 2 months) and not just EOD chart.
And yes, never average your loosing trade - if you dont have stomach to bear initial losses (may or may not arise), I would advise to use OPTIONS, where you know from beginning what will be your limited maximum loss, and you have time till expiry to let your trade go through. Also, going for half of your normal quantity (which you trade with for intraday trading) is advisable.
This is not intended for those who have just started trading nifty, or those who have just begin to learn/read/comprehend charts....
This is for people like my member-friend Lalith who realise the risk-reward in a contra-trend positional trade, and wish to add something to their bread-&-butter intraday trading.
I again stress - positional trading should be done sometimes along with intraday trading, but contra-trend positional trading is very risky (but rewards may be higher sometimes, if your entry level is good).
