Hello,
Please keep aside everything you know and look at a Stop-Loss(SL) order as just any other order.
There are 2 types of Stop-Loss orders:
1. SL order (Stop-Loss Limit) = Price + Trigger Price
2. SL-M order (Stop-Loss Market) = Only Trigger Price
Case 1 > if you have a buy position, then you will keep a sell SL
Case 2 > if you have a sell position, then you will keep a buy SL
In Case 1, if you have a buy position at 100 and you wish to place a SL at 95.
a. SL-M order type - you will place a Sell SL-M order with trigger price = 95.
Here, when the price of 95 is triggered, a sell market order will be sent to the exchange and your position will be squared off at market price.
b. SL order type - you will place a Sell SL order with price and trigger price. Since your order needs to be triggered first, the (trigger price > price.) Here, this order type gives you a range for the Stop-Loss.
Lets assume a range of Rs.0.10(10 paisa). Here, you can keep trigger price = 95 and price = 94.90. When the price of 95 is triggered, the sell limit order is sent to the exchange and whatever is the market price between 94.90 and 95, your order will be squared off at that price.
* The disadvantage of this order is that if the market falls steeply, then after 95 is triggered and before the Sell Limit order of 94.90 is sent to the exchange, if the stock price is already below 94.90, then your Stop-Loss order will still be open and your losses could be much higher.
You will have to use your discretion whether to use SL or SL-M depending on the market scenario.
In Case 2, if you have a sell position at 100 and you wish to place a SL at 105.
a. SL-M order type - you will place a Buy SL-M order with trigger price = 105.
Here, when the price of 105 is triggered, a buy market order will be sent to the exchange and your position will be squared off at market price.
b. SL order type - you will place a Buy SL order with price and trigger price. Since your order needs to be triggered first, (the trigger price < price.) Here, this order type gives you a range for the Stop-Loss.
Lets assume a range of Rs.0.10(10 paisa). Here, you can keep trigger price = 105 and price = 105.10. When the price of 105 is triggered, the buy limit order is sent to the exchange and whatever is the market price between 105 and 105.10, your order will be squared off at that price.
Alternate use of SL order:
Since Sell SL orders are used above your buy price and Buy SL orders are used below your sell price, you can use these order types to Buy above LTP(Last Traded Price) and Sell below LTP.
1. To buy above LTP, you can place a Buy SL order with the price at which you want to buy.
2. To sell below LTP, you can place a Sell SL order with the price at which you want to sell.
Cheers!
