How to use limit order as a market order?

A trade that gets executed at a far away price from the current market price is called a 'freak trade'. Freak trade occurs owing to a shallow market depth (low liquidity). A freak trade can also occur if your trade coincides with a large market order.

When you place a market order, there is always an inherent risk of losing money due to a freak trade.

A limit order on the other hand guarantees price execution at a specified price (avoids freak trade), but there is no guarantee of the order fill itself.

But there is a way to have the best of both order types, i.e to enjoy the price protection of a limit order (hence no freak trade) and also enjoy the order fill guarantee of a market order.

Use limit orders as market orders.

If you place a buy limit order with a price above the current market price, your limit order will act as a market order, with market protection of the limit price you have mentioned.

So for example -

Current market price of ITC = Rs.241

Limit buy order = Rs.245.

Since the price is Rs. 241 and you intend to buy at a higher price, this order will act as a market order and execute immediately. Here, all quantities up to Rs.245 will get filled.

In this case, if there is a large market order coinciding with your order, resulting in a price spike, then your limit order will ensure you are protected against the spike by limiting your buy price to 245 and not beyond.

Similarly, if you place a sell limit order with a price below the current market price, your limit order will act as a market order.

For example, assume you are long on Nifty 17500 CE and its current price is Rs.185. You place a limit sell order at Rs. 180.

Since the current market price is Rs. 185 and you are placing the limit sell order at a lower price, this order will act as a market order and execute immediately. Here, your order will sell all available quantities up to Rs. 180.

In this case, if there is a large market order coinciding with your order, resulting in a price spike, then your limit order will ensure you are protected against the spike by limiting your sell price to 180 and not lower.

Note: The further the limit price from the current market price, the lesser the chances of your limit order going pending, but higher the potential impact cost.
