The minimum Trading Volume
At Tradeview, all transactions occur in increments of $1k and 1 ounce in precious metals. Tradeview does not distinguish between mini and standard accounts.
As Tradeview trading platforms show 1 lot as 100,000 units, the minimum trading volume in this case would be 0.01 lot.
If you have selected the maximum leverage 1:400 for your trading account, then you will be required about a few dollars or more to hold a position of 0.01 lot.
But you should also need to take profit/loss into consideration as it will directly affect your margin levels.
The maximum Trading Volume
On Tradeview MT4 platform the maximum size per order is 7.5M notional value(75 standard lots) for major FX pairs.
Please keep in mind that your execution volumes are limited by your available trading margin.
For your information, Tradeview’s trading server will trigger Stop-Out at 100% of margin level in your trading account.
Tradeview will send orders to the market as you wish though, it is your responsibility to take care of your loss.
‘Larger trading volume’ leads to ‘Higher slippage rate’
Although Tradeview allows its traders to order up to 75 lots of position, you must know that it is a large trading volume.
Generally speaking, there are only about up to 30 standard lots (3,000,000 units) of market liquidity available per price.
If there is no enough market liquidity to execute your order, then the system automatically finds for the next available price (which can be negative or positive for your position) and execute.
It is called ‘Slippage’ and it is an inevitable condition in any financial markets.
