Is this a foolproof trading strategy?

i have two operations, BTC / USDT & BTC / BUSD

BTC / USDT = Long operation, 30x leverage, with a capital of 120 USDT, Per operation it does 635 USDT With a maximum of 2 operations at the same time. Lets say it buys at 26.000, Liquidation price would be 25133.33$

BTC / BUSD = Short operation, 30x leverage, with a capital of 120 USDT, Per operation it does 635 USDT with a maximum of 2 operations at the same time. Lets say it buys at 26.000, Liquidation price would be 26865$ ish

Lets say bitcoin right now is at 26, both buy, and it rises to 26900., On long, i would have a profit of 103% while loosing 120 USDT, wich would be 3.6 USDT up, And aproximately the same would be if it reached 25100.

Now, i would break even if it reached any of the liquidation prices, but as long as it does NOT reach either and it goes back, id be winning.

And if it does skyrocket, or fall a lot, then id still be winning, because my gains would be more than 100% if the price is greater or lower than either of the liquidation prices.

So what would be the risk then? The only risk i really see is closing a deal when the other one is still open, if the price does not come back then i would be loosing. Example: both buy at 26000, price goes to 26500, i sell the long one but i still have the short one on loss, and instead of the price going back to 26000 it keeps rising and i loose everything on the short trade.

if im above the liquidation price on either, the trade would close itself and i would instantly loose the 125usdt, but as long as i close the deal at the liquidation price (or greater) id be breaking even or having a profit.
